A revolution is well underway, but it doesn’t have anything to do with immigration, tariffs, or AI. Instead, it’s a quantum leap in the thermal imagery technology, deployed in that backwater of hunting that takes place at night. 

As companies both miniaturize the size and increase the capabilities of their thermal sensors, image-correcting software, and high-resolution displays, the amount of digital technology packed into a modern thermal scope is the equivalent of that of an early NASA spaceship.

Even entry-level thermal scopes have impressive tech packed in their flimsy housings.

But pay close attention to the top-end products in this review. They’re expensive because they are built around the most sophisticated components available to the consumer market. But one of the dominant trends in thermals is that this leading-edge tech quickly descends into other, more affordable, product lines and into competitors’ catalogs.

While our testing rewards these higher-performing thermals — after all, there’s a demonstrated benefit to higher-resolution thermal cores, larger germanium lenses, and proprietary image-sharpening algorithms — our testing also demonstrates that there’s a decent thermal scope for every budget.

The entry-level models might leave you with a headache and a desire for a sharper image, but they’ll at least get you in the nighttime hunting game.

Here are the top thermal scopes of the year. Note that it’s an invitational test; we didn’t invite every product and brand, but we endeavored to test a variety of models, brands, and prices to give readers an idea of what’s on the market, and the attributes they should consider as they buy a thermal scope.

• Integrated ballistic calculator
• Best display resolution in class
• Internal/external battery dual-power system
• 9-plus hour run time
• Top-turret operation is fast and simple
• Rounded display resembles traditional daylight scope
• Red and green monochrome palettes reduce night-blindness
• Ships with 30mm ADM Recon Mount
• Extremely easy to zero
• 5-year warranty

The future of thermal hunting is here, and it’s gonna cost you. The new -class Adder V2-60 from AGM Global is bright, clear, sensitive, and fully capable of making range-adjusted nighttime shots out to 1,000 yards. The price for that performance? An eye-watering $7,300.

Anyone who has ever used a thermal scope has wanted it to perform like a daylight scope. But the technology that converts temperature variation into visible images is so full of noise and distortion, from the processor to the software that sharpens images to the digital screen that projects them to your eye, that thermal hunters have to accept headaches, eye strain, and astigmatism as a price for seeing into the night.

The V2-60 is the closest I’ve come to a thermal scope that delivers an image that’s in the same galaxy as that of a traditional scope. It achieves that performance with a souped-up × sensor, one of the most powerful in the class, and a high-resolution × digital display that is crisp and contrasty. But it’s AGM’s software that fuses these components into an almost pleasing image.

Add a blazing-fast 1,000-meter through-the-lens laser rangefinder, cold-and-warm viewing modes that reduce eye strain, an on-board ballistic calculator that displays distance-adjusted holdover, and a 9-hour run time, all packed in a fairly trim 30mm aluminum tube.

All that performance combines to make the AGM Adder V2-60 the consensus winner of our Editor’s Choice as the top thermal scope of the year.

But there’s more. Two features of the Adder that may get lost in its specs include a ½-power magnification step. Most thermals have what’s called “step zoom,” in which the magnification doubles with every tap of the button. Those big steps can create large gaps in the zoom range, but the Adder’s incremental zoom creates a much more usable magnification range. Second, that 1-inch hyper-sharp display is slightly rounded, giving users the visual perception of looking through a traditional scope.

The AGM wasn’t without its flaws. Tester Alex Robinson struggled with unexpected shut-downs.

“When the external battery was low, but the internal battery was full, the scope shut off repeatedly,” he noted. 

The AGM had hot competition from Nocpix’s new -class ACE S60R scope and Pulsar’s Thermion 2 XL50. On paper, the Nocpix has the more impressive array of features. But here’s where the power of image-enhancing software tips the scales. In head-to-head-to-head comparisons, testers unanimously noted that the Adder had the clearest and least eye-straining image. That’s a squishy but important consideration for thermal users who might be behind their scopes for hours at a time.

Still, there’s the issue of the high cost of the AGM. Readers who aren’t immersed in the realities of thermals might be put off by the price. But readers who know that, just as with traditional optics, with thermals, generally, the more you pay, the more you get. That’s certainly the case with the remarkable, full-featured, investment-quality AGM Adder V2-60.

Great Buy Thermal Scope: Athlon Cronus ATS Pro 25P-250

Pros

• For around $700, a bargain
• 9-hour run time with internal and external batteries
• Includes single-point QD rail mount
• Single-button and rotary selector operation
• At 8 inches, perfect for carbines
• Easy to zero and calibrate

Cons

• Power/selector button is finicky
• Battery cap hard to keep closed
• Underwhelming clarity
• Clunky mobile app

Let’s start with what this entry-level thermal isn’t. It isn’t very clear or very sharp. It isn’t going to allow you to shoot out to 500 yards, or even past 250 yards. It isn’t going to win any hunting competitions or design awards. It feels a little flimsy.

But it is one of the best bargains in the thermal market, and is fully capable of getting you on coyotes and pigs out to near 200 yards. It will easily capture video and photos and transmit them to your . It comes with a solid rail mount. It’s easy to operate. And it gives hunters an opportunity to dip their toe in the thermal category without taking out a second mortgage.

Given the astonishing capabilities – and prices – of its competition, we had low expectations of the Athlon. The ATS Pro’s 256-microbolometer sensor is among the lowest-resolution cores in our test. To put that in context, the -microbolometer sensor of AGM’s Adder has five times more resolution. It’s also 12 times more expensive.

The $600 entry point for the Athlon Cronus ATS Pro 25P-250, combined with its decent performance, is what makes it so appealing, and what earned it our Great Buy award for the highest Price/Value score in the group.

If you want a bit more resolution, consider Athlon’s Cronus ATS Pro 35P-400, with a 400×300-pixel core. That unit will cost you about $1,000; in our view the increased performance doesn’t quite justify the upcharge.

The 25P-250 Cronus isn’t racing for the bottom. Its one-button and rotary selector operating system is fast and intuitive. Double-tap the power button to reveal the menu, use a rotary collar inside the eyepiece to navigate its options, then hit the power button to make selections. The scope has 10 selectable reticles, five based on MOA and five based on MIL dimensions adjustments, and seven color palettes. While the Athlon doesn’t exactly have a ballistic calculator, it does have the ability to customize reticles to various holdover values at specific distances.

Athlon’s mobile app is a little clunky — among its other shortcomings, it only works in horizontal mode — but the photo and video transfer is easy.

The single-point rail mount is decent, and makes for fast mounting, but it’s not a precision attachment. We also had fits keeping the battery cap attached. That’s a small quibble, but a meaningful shortcoming since it reduces operating time. And we worried that the plasticky build might not be up to the sort of bump-and-grind abuse thermal hunters routinely demonstrate.

But those are speculative fears. What we determined in testing is that this is a thermal that’s absolutely worth the money.

Nocpix ACE S60R

Pros

• 1-3x ocular magnifier
• Rounded display increases clarity and detail
• Simple single-button/single/dial operation
• N-Link system connects to other Nocpix devices
• 1,300-yard through-lens laser rangefinder
• 32GB on-board image storage
• Ability to “hot-swap” batteries without shutting down device
• Ballistic calculator displays range-adjusted reticle hold
• Standard 30mm tube
• 5-year warranty

Cons

• Very expensive
• Inconsistent connection to mobile app
• Glitchy rangefinder performance on inclined targets

Every tester (and every tester’s thermal-using buddy) was more excited to put their hands on this new flagship scope from Nocpix than any other thermal. It’s gotten tons of hype not only for its exceptional performance but for its astonishing price of just under $8,000.

While it would be easy to dismiss that price as a stratospheric extravagance, there’s a lot in this scope that justifies it. Let’s start with the stunning resolution. It ran head-to-head with the AGM Global’s flagship and just ahead of Pulsar’s remarkable Thermion2. Its -class thermal core generates a rich and detailed image, but it’s the high-resolution -pixel display that makes looking through this scope almost like an AI-rendered video, so sharp and vibrant are the images it delivers.

Like the AGM Adder, the Nocpix ACE uses a slightly rounded display that imitates the circular field of view of a daylight scope, a design that somehow reduces eye strain. It was also one of the few scopes that was useful in daylight. Adding to the conventional feel is the Nocpix’ 30mm tube, which accepts standard scope rings, and a very smart magnification ring on the ocular lens. This manual magnification enables users to add between 1-3-power in addition to the digital magnification without causing any reticle shift. It’s a very handy feature when you want to add just a bit more magnification to a scene without doubling the digital zoom.

We also liked the easy operation of the ACE S60. A button in the eyepiece powers on the unit, starts and stops recordings, and fires the laser rangefinder. For other menu items, simply tap the button on top of the elevation turret, then turn the turret to navigate selections. And, man, are there a lot of selections.

Among its more noteworthy attributes: an onboard ballistic calculator that adjusts the reticle to your specific load’s impact at distances determined by the rangefinder. Once you have your dope loaded, simply range a target, and you’ll get a range-adjusted holdover. The through-the-lens laser rangefinder is fast and fairly accurate, though some testers noticed incorrect ranging at severe angles.

The ACE S60R also utilizes Nocpix’s new N-Link, a Bluetooth-enabled frequency that communicates with other Nocpix devices. A user scanning with the Nocpix Quest thermal binocular, for instance, could range a target and transmit that information wirelessly to the ACE scope, where it would show up as the range-adjusted reticle hold. It’s a slick system that elevates the capabilities of a hunting team and is especially handy in the fast-paced coyote competitions that tester David Stroud competes in.

Stroud, who uses a variety of high-end scopes in the Texas predator-hunting circuit, was especially emphatic about the talents of the new -class ACE.

“I have the ACE H50R and have used it for the past few months, but the S60R is on another level, entirely,” Stroud noted. “I will probably invest in the ACE S60R as my next thermal.”

We had only a few quibbles with the Nocpix, but they were enough to knock it out of the top spot by a single point. The most common problem was inconsistent connection to the mobile app, and then getting the app to refresh with our ballistic data.

But the Nocpix is the scope that other thermal weapon sights will be judged by. It’s not only the flagship for Nocpix, but for the entire industry. An investment in the ACE S60R is soothed a bit by its durable build and its remarkable 5-year warranty. Even more remarkable: warranty claims are addressed at the brand’s Dallas-area service center within five days, so users won’t be without this remarkable scope for long.

Pulsar Thermion 2 LRF XL50

Pros

• Durable aluminum alloy build
• 30mm tube accepts standard rings
• 2-battery (1 internal, 1 external) operation
• Ambidextrous focus control
• Simple 3-button operation
• Integrated ballistic calculator
• Simple zeroing procedure
• Rich image contrast
• Connectivity to excellent Stream Vision 2 app

Cons

• Proprietary batteries
• Bulky rangefinder module
• Glitchy app connectivity

The third in our trio of full-size flagship scopes, to include the Adder from AGM and the ACE from Nocpix, Pulsar’s Thermion 2 is the OG of the category. It set the design and performance standards that its competitors have adopted, and in some cases, exceeded.

The latest version of the venerable Thermion2 is a -class gem. It features an excellent laser rangefinder, very good optics and image-enhancing software, and one of the easiest, most intuitive menu navigation in the class. With a 1.75x base magnification and a top-end mag of 14x, it has the close-in capabilities for hog hunters who generally engage targets inside 200 yards, but it has the resolution and magnification to take coyotes out to 500 yards and beyond.

Appealing attributes of the Pulsar include the smartest focus control in the category, textured dials on either side of the bulky rangefinding unit that focus the image. Most scopes have an objective-bell focus that’s a long arm reach for users, but the side focus works for both right- and left-handed shooters and enables fine focus without pulling the rifle off your target. We also liked the 3-button navigation system with buttons on the eyepiece.

Pulsar’s picture-in-picture feature, in which users can magnify the portion of the image that’s covered by the reticle while leaving the rest of the image at base magnification, is also noteworthy. The P-in-P resolution is sharp, the aiming point highly visible, and allows users to have both situational awareness with the wide field of view and pin-point precision with the magnified aiming point.

“This is the scope I hunted with the most and I had no issues detecting or identifying coyotes out to 200 yards. But, I also hunted with Nocpix Ace which, is much more sophisticated for an extra $1,000,” says Outdoor Life‘s gear editor, Scott Einsmann.

We didn’t like Pulsar’s proprietary batteries, though. While most thermal brands have migrated to interchangeable lithium-ion batteries, particularly large-capacity cells, in addition to their internal rechargeable batteries, Pulsar’s APS batteries fit only in the brand’s chargers and battery compartments. They work well enough, but lose one at your peril, and learn to carry the Pulsar charger with you in the field.

Unlike other brands, which list only the sensitivity of their thermal core — this is the NETD, the value of which is listed as mK, or millikelvin, in each thermal’s specs — Pulsar adds a sNETD, which stands for system sensitivity. It’s an important distinction, because it describes the image delivered to the user’s eye, not just the image rendered by the sensor. I mention this because the image of the -microbolometer Pulsar is every bit as sharp and contrasty as that of the -class AGM and Nocpix. Some testers thought the Pulsar was even better.

That’s a testament to a brand that has built thermal scopes for decades and which still dominates the category. The XL50 is built like a tank and will reveal targets as far away as you want to shoot.

Most Versatile: Nocpix SLIM H35

Pros

• Dual viewer/sight functionality
• Quick-release Pic-rail mount
• >1 MOA point-of-aim shift through magnetic alignment
• Ambidextrous one-hand operation
• Powered by common rechargeable batteries
• Intuitive 3-button navigation
• Durable magnesium alloy chassis
• Perfect configuration for AR carbines

Cons

• No rangefinder
• Middling resolution
• QD mount isn’t particularly precise

You have to use this handy, versatile, and priced-right thermal to fully appreciate its abundant talents. It’s a hand-held monocular, configured for decent mid-range scanning. But it can snap onto a mount in seconds, with the aid of a magnet for indexing, and the SLIM becomes a capable rifle sight. We tested this function for return to zero and it was right on after removing it and putting it back on. 

This dual-use unit is the answer to those hunters who recognize that, in order to be in the hog- and predator-hunting game, you need both a thermal viewer and a thermal scope. But who has the budget to afford both? This single unit might not be the ideal of either platform, but it’s good enough at both that budget-minded hunters should seriously consider it. In fact, it was a close second to the Athlon Cronus ATS Pro 25P-250 for our Great Buy award.

Tester Alex Robinson crystallized its place in the category.

“This seems like a great option for a new night hunter or a pig hunter who will be shooting at 100 yards and in. I like the easy functionality, small profile, and the ability to remove it from a rifle and use it as a handheld viewer.”

As in any Outdoor Life gear test, testers identified some shortcomings. First, its 640-class sensor is pretty good for hog hunting inside 250 yards, but it’s not sharp enough for the long-range shooting that characterizes most nighttime coyote hunting. Second, the quick-release Pic rail mounting interface is fast, for sure, and it’s pretty precise, but it’s not a system that will warm the hearts of long-range precision shooters. Nocpix claims a 1 MOA deviation in return to zero between the transition from viewer to scope, and that’s about right. That +/- is right in line with the expectations of most hog hunters.

This is not a ding on the unit, but rather on the Nocpix digital ecosystem — every tester tore his hair out with infuriatingly frequent firmware updates. Another demerit: no rangefinder.

I tested the value proposition of the viewer-to-scope capability, and timed the transition. I used the SLIM H35 as a hand-held viewer, identified a steel coyote-sized target at 200 yards, slapped the Nocpix on my 22 Creedmoor, cinched it down, reacquired the target, and then made a first-shot hit all within 13 seconds. I recorded no point-of-impact shift.

We liked the fact that the SLIM uses standard flat-top batteries, has a smart magnetic charging port for quick power-ups, and has recoil-activated filming.

In short, this isn’t a full-featured scope or viewer. But it’s not intended to be. Instead, it’s intended to be a one-and-done do-it-all thermal that can capably transition from a viewer to a rifle sight.

Best Mid-Priced Thermal Scope: Guide TU651 LRF

Pros

• Traditional riflescope design
• Easy menu navigation with top turret
• Single-button LRF operation
• Left-side zoom control is fast and easy
• Impressive on-board memory

Cons

• Objective-bell focus is overly tight
• Too-frequent refreshes
• Too-tight objective lens focus
• Target IR mobile app is clunky

This otherwise very good thermal scope raises a critical question for potential buyers: Do you spend $4,000 for a 640-class scope that is serviceable, or do you spend twice that amount for a thermal that will blow your hair back?

It’s the same question that shoppers of traditional daylight optics ask. Reduced to its essence the question is: Do you settle, or do you invest?

Those who settle will get pretty good mid-range performance from the Guide TU651. The ergonomics are generally excellent, and they include a fast and intuitive top-turret menu navigation, a left-turret zoom control, and a single-button laser rangefinder operation on the back of the ponderously large ranging unit. The durability is equally satisfying; a stout 30mm aluminum tube that mounts on standard scope rings.

Our complaint with the TU651 is its guts. The 640-pixel core is good, but compared to the new class of -microbolometer sensors that is coming to the market, its resolution and image quality is anemic. If you’re spending a bit over $4,000, you don’t want just “good.” Happily, the Guide brings enough other talents to the game that its resolution won’t be distracting.

The intuitive operation is its superpower. Its interface is fast and simple, and the laser rangefinder is both powerful and fast, though the nearly 2-inch-tall LRF module ruins the sleek lines of the Guide. Capturing images is as simple as pressing a button on the eyepiece, and zooming the magnification with the control where you might expect to find an illumination or parallax focus on a traditional scope, on the left turret, is an excellent feature.

Operationally, each tester complained about frequent freeze-ups as the digital image refreshed, and a couple said the Target IR mobile app was hard to navigate. Still, there’s a lot of performance in this big, honest thermal scope. And if you don’t like the price of the performance delivered by the 50mm TU 651, Guide has nearly a dozen other models with a combination of objective lens size and thermal resolution to fit your budget and your performance expectations.

Best Carbine Thermal Sight: SIG Sauer ECHO SV35

Pros

• Cantilevered Pic rail
• Ships with premium hard case
• Connects to SIG’s BDX 2.0 system
• Connects to Applied Ballistics dope
• Runs on twin rechargeable batteries
• 11-hour run time
• Covered by Sig’s lifetime guarantee

Cons

• Mount is hard to use with bolt guns
• Useful range limited to 250 yards
• Stingy eyebox

Sig Sauer’s long-awaited entry into the thermal market isn’t a single product. It’s three versions of the ECHO line, all built around the same 640×512 thermal core. The company has a 25mm clip-on, a 50mm weapon sight, and this 35mm sight. The 50mm version costs another $500, which isn’t that much given its additional reach and optical horsepower.

The 35mm version is a solid freshman effort, and it seamlessly folds many of the products from the Sig ecosystem into a workaday thermal. There’s the Ballistic Data Exchange (BDX) that wirelessly shares aiming dope between devices. There’s Sig’s KenETHIC energy indicator that allows a hunter to set a foot-pounds threshold for distance-adjusted shots. There’s Sig’s proprietary optical coatings and what Sig calls its Lightwave DSP, which is a fancy term for a signal processor that’s supposed to provide fast refresh rates.

The ECHO is also built like a Sig, which is to say it’s a brick, in all the best ways. Its aluminum-alloy chassis is built for the abuse night hunters dish out to devices, and its power source, twin rechargeable Li-Ion batteries, keep it firing for an impressive 9 to 11 hours. Also on the plus side is its 1,000-yard integrated laser rangefinder.

The 7-inch integrated cantilevered Picatinny rail is a great attribute, and it makes the ECHO a boon companion for full-rail AR carbines. But, it makes mounting the scope to a bolt rifle a relative nightmare. We couldn’t run the ECHO on our Horizon 22 Creedmoors because the rangefinder module collided with the bolt lift.

While we’re on demerits, the Sig was optically underwhelming. It was handy inside what the test team calls “pig range,” the inside 200-yard operating range of most feral hog hunters. But it struggled to define even deer-sized targets beyond 300 yards, which makes the 1,000-yard laser rangefinder a little extraneous. Testers dinged what they called the “stingy” eyebox and the eye-watering display during long hunting sessions.

“I needed Visine after about an hour behind the Sig,” noted tester Derrick Ratliff.

We like the 4-button menu navigation. It’s a smart and intuitive system, with brightness, image capture, menu-access, and laser rangefinder buttons all around the central control button. With so much of the industry migrating to 3-button or even 1-button operation, the 4-button arrangement takes some practice but in the field it’s fast and sure.

In all, it’s a decent sight. We might recommend this 35mm version lose the rangefinder and become a slim and nimble sight, while the 50mm version could transition to the mid- to long-range thermal. But if you’re an AR hunter looking for a plug-and-play thermal sight, the ECHO is a great choice, and the fully transferable lifetime warranty makes it one of the safest investments in the thermal category.

Best for Hog Hunting: AGM Rattler V3 50-640

Pros

• Integrated rail mount
• In-lens laser rangefinder
• Shot-activated video recording
• Slim and compact form factor
• Impressive detection range
• Integrated ballistic calculator
• 5-year warranty

Cons

• Proprietary batteries
• Disappointing resolution
• Puny display

We’re not quite sure how AGM Global has so many models at so many different resolutions, but our take-away is that if you don’t like the image or the price of one AGM model, shop around, because the brand probably has a thermal for every performance and price point.

The V3 version of AGM’s venerable Rattler builds on the celebrated line, adding an in-lens laser rangefinder, a high-resolution -class display, and an unbelievable 3-mile detection range.

All those attributes are great on paper (or on a website) but in our experience, the new Rattler is an excellent inside-250-yard hog sight but a disappointing 400-yard coyote sight. Those might seem like arbitrary metrics, but in the field they’re meaningful. We could identify, classify, and target game inside that wild-hog boundary of about 200 yards. But we struggled to do the same with those cagy coyotes, which generally won’t come inside the 400-yard ring unless conditions are just right. That maximum operating range gave testers the consensus conclusion that the Rattler V3 is a nearly perfect hog-hunting scope, but it struggles at coyote distances.

We loved the compact form factor that makes this a capable mount-and-shoot AR carbine scope and its overall functionality, which includes its shot-activated recording, onboard ballistics calculator, and connection to the excellent AGM app. But we tested the 50mm Rattler against the 35mm Sig ECHO, and it was hard to find meaningful differences, despite the bigger AGM lens and somewhat better image-enhancing software.

Still, the AGM has some very appealing close- to mid-range attributes, which includes a 4-button menu navigation, quick refresh, smooth focus, and what AGM calls its “image boost” software that sharpens and adds contrast to its picture.

If the V3 version of the Rattler is too rich for some hunters, consider more price-point Rattlers. It’s a proven and capable platform and if AGM has demonstrated anything, it’s that it can deliver a product for any combination of budget and thermal expectation.

Most Durable: Armasight Commander 640

Pros

• Ships with Kinetic Sidelox rail mount
• Tough metallic-alloy housing
• 3-year warranty
• Double-tough gaskets and build
• Choice of simple and practical reticles

Cons

• No mobile app or wireless media transfer
• Limited 4-hour run time
• Range limited to about 200 yards

Like Trijicon’s thermals, Armasight is courting the consumer market after a robust track record of providing thermals to military and law-enforcement agencies. That martial DNA is on full display with the Commander, which is built around a shock- and drop-proof metal-alloy chassis and battery and SD-card compartments that are gasketed, tethered, and otherwise immune from user abuse.

The 640-class sight is designed for use with an AR carbine. Like the Sig ECHO, it has an integrated cantilever mount that’s optimized for full-length rails. The compact form factor is similarly sized for use with an AR-15-sized carbine, though we had a ball with it on a .22 rimfire. Also like Sig, the Commander shares design and operation with other Armasight thermals; once you learn to navigate this unit, you can seamlessly transition to any of its 640-class models.

The Commander is a decent close- to mid-range sight, but also like the 640-class Sig, we struggled to define targets beyond about 250 yards. The Armasight also lost points on its relatively limited run time of 4 hours, as it’s powered by twin CR123 batteries. And the brand doesn’t have a mobile app or ability to wirelessly connect. Instead, media is stored on a micro SD card and must be manually transferred to a device.

Those aren’t deal-breakers, but they hold the Armasight back from consumer expectations. What the Commander640 brings, though, is simple and reliable operation. I mentioned its session aboard a rimfire; this might be the most capable varmint-removal tool in our arsenal. Night hunting for rats, raccoons, and skunks suits its compact form-factor, its short-range talents, and its fast operation.

Best Reflex Sight: Holosun DRS-TH

Pros

• Excellent red dot
• 10 hours thermal run time
• 50,000 hours red-dot run time
• Integrated rail mount

Cons

• At 18 ounces, bulky
• No wireless media transfer
• No mobile app

Holosun has married its excellent red-dot technology with a miniaturized thermal unit in the DRS-TH, which enables users to capably deploy handguns or self-defense shotguns in nighttime scenarios. Our testing was geared to tease out the talents of mid- and long-range thermal scopes, so we weren’t able to get a full work-up on the Holosun.

But we strapped the unit on our 22 Creedmoor ARs and had a ball with short-range plinking in quick target-acquisition scenarios. We operated the DRS-TH in separate red-dot and thermal modes, but the unit can run in dual-use mode where users can dim down the red dot to a barely visible aiming point and use the thermal for low-light target detection and recognition. It’s a fast and effective combination.

The unit has a 2 MOA red dot with eight brightness settings as well as four night-vision settings. Users can choose between a 65 MOA circle or 32 MOA depending on how large you like your donut of death. Or deactivate the circle and use just the red dot for precision work. DRS-TH has a 1x base mag but magnification steps to 3x and 5x. Display options include white hot, black hot, outline, and highlight modes.

The small size of the Holosun does have some drawbacks. It doesn’t have a Bluetooth transmitter, so it doesn’t connect to a mobile app. Users can record video and then transfer it via USB cable. And the small controls and separate lens covers take some practice to quickly deploy the sight in the field.

But the display, at 1.25x.98 inches, is surprisingly large for such a micro sight, giving users a fairly wide view of the world. Given those dimensions, plus all the technology packed into this sight, the unit is a chunk. But it’s just about perfect for an AR, pistol-caliber carbine, or home-defense shotgun.

The most consistent and enduring dig on thermal optics is that the image they deliver is grainy, dull, and unfocused. Even in the best conditions, these devices can’t match the sharpness of traditional optics. The resolution of thermals’ sensors and displays are far less than that of your mobile or laptop computer screens.

The reason, of course, is that the image that reaches your eye behind a thermal is a digital depiction of reality, and the factor that limits sharpness is a combination of pixels and processors that turn tiny differences in detected temperature into images our brains can comprehend.

It’s expensive to boost digital resolution. That’s why thermals with high-resolution sensors cost much more than those with lower-resolution sensors. Many thermal brands “cheat” by providing software solutions that sharpen and brighten images. But the new InfiRay Outdoor BOLT TX60C thermal scope features a premium × sensor that’s double the resolution of most of its competitors. Even more remarkable, its display resolution is × and round to provide corner-to-corner clarity. That investment in image processing results in a noticeably sharper and more resolved image compared to the InfiRay’s peers.

The optical horsepower of the BOLT puts it in a class by itself, but it has tons of other features that make it a fast, smart, intuitive, and highly effective hunting and shooting rig. Taken in total, the InfiRay BOLT TX60C handily wins our Editor’s Choice award as the top thermal scope of the year.

You’ll pay for this level of performance. Priced at $6,999, the BOLT is an expensive product, but it not only represents the next generation of thermals, but considering all its talents, it’s not out of line with the price of lower-performing competitors.

Operationally, the BOLT is simple and intuitive. In place of a traditional scope’s elevation turret, the BOLT has a push-and-turn control that operates its extensive electronic menu. Near the eyepiece is a 3-button control that activates the photo/video mode, palette choice, and image brightness. The controls are easy to use with gloved hands, and riffing between modes and menu choices is among the simplest of any unit in our test.

Externally, the BOLT has an objective lens focus with a retractable throw lever that makes fine-tuning focus easy and fast in the field. The unit has a recoil-activated video mode that automatically records 30-second clips before and after a shot. And the InfiRay has one of the simplest battery systems in the field. Users can plug the scope into a wall mount with a USB cable, or they can use standard batteries, swapping them in and out in the field. Add an inclinometer, choice of seven reticles, seven color palettes, and a compass-activated directional orientation, and this thermal scope wins on attributes alone.

Add a best-in-class quick-detach Picatinny rail mount, and you have an investment-grade thermal that should provide years of excellent operation and imagery, with software upgrades provided by the excellent InfiRay Outdoor app.

We greeted InfiRay’s claim that the RICO Hybrid scope could detect deer-sized objects out to 3,600 yards with a big dose of skepticism. After all, that’s a lot of real estate for any optic, especially in the veiling darkness of night. But at this year’s Outdoor Life optics test, we used the Hybrid to scan the miles-distant face of the soaring Rocky Mountain Front, and damned if we didn’t detect an animal — it might have been a cow moose or a young bull elk — feeding out of a cottonwood bottom and grazing on a foothill pasture, at 1 in the morning.

The next day, we ranged the spot. It was two miles away, 3,311 yards, to be exact. InfiRay’s claims are spot-on. This is a serious, expensive, and very capable thermal scope, and if you have $8,000 laying around, you should run to a retailer or internet site to buy this. It’s that good.

It’s actually a little too good. We’ve been used to rating the relative merits of thermals based on their sensor and display resolution. Those with higher-resolution innards generally deliver better imagery, and since this is a test of optics, image is everything. Well, almost everything.

This is one of the few cases in thermal devices where lowish sensor resolution doesn’t necessarily result in disappointing performance. The RICO Hybrid scope has a fairly pedestrian sensor resolution of 640×512 microbolometers, which should produce a forgettable image. But InfiRay has combined a huge 75mm objective lens (a 50mm lens is also available) with a high-resolution ×-pixel display, and a sophisticated digital processor to boost the image, creating sharp, immersive, three-dimensional images out of quavering nocturnal targets.

The Hybrid has a number of other appealing features for thermal hunters. It ships with a built-in Picatinny mount that easily mates to most rifle rails, and it has a couple of other integrated Pic rails that accept accessories, including a sold-separately InfiRay laser rangefinder module. Its controls are simple and easy to use at night. Those include a dial focus control that’s easy to use with gloved hands, and a smaller dial that controls the internal menu.

The device captures both photos and videos, and sharing them through the InfiRay Outdoors app is easy and simple. Users can also choose to manually download images stored on the 64 GB onboard memory of the RICO. The unit has a recoil-activated video capture mode that allows users to capture 30 seconds before and after the trigger is pulled. Run time on the rechargeable batteries is about 6 hours, depending on how much recording you do, and given the great image capture of this device, you’re going to do a lot of videoing.

There are some important downsides to this hefty thermal scope. The first is its physical size. It weighs 2.8 pounds, so you’d better have a good bipod or tripod to handle the weight of the optic and your rifle. And it’s undeniably expensive, especially when you consider that a laser rangefinder will cost another $800 to add a Bluetooth-connected rangefinder to this unit.

But for a thermal scope that will fully reveal the far-away world at night, and will help shooters place bullets thanks to customizable reticles, this scope is in a class of its own. When you consider that it also performs as a very competent hand-held thermal viewer, the sticker shock is a little less, well, shocking.

Key Features

• 640×480-microbolometer thermal sensor
• 3x magnification
• ×-pixel display resolution
• -yard detection range
• 16-gigabyte onboard memory
• Lightweight – 18 ounces
• Kit includes adapters for wide variety of slave scopes

For some reason, American hunters haven’t fully embraced the elegance, simplicity, and versatility of clip-on thermals. Our European peers pioneered the use of clip-ons, which use traditional daylight scopes as slave optics, with the thermal unit literally “clipping-on” to the objective bell of the scope. The design dominates in Europe, largely because hunters don’t have to swap out their main rifle scope in order to add thermal capability.

That’s probably because gun ownership is limited in Europe, and most hunters there don’t have a dedicated night-hunting rifle.

But it really is a sensible way to add thermals to your existing arsenal. Clip-ons tend to be less expensive than dedicated thermal scopes, and they often have better electronics and recording capabilities because they’re not dedicating so much room and battery power to generating images.

If you’re looking for the best of the clip-on world, Pulsar’s Krypton2 is a good place to start. It features an excellent 640×480 12-micron sensor, a high-resolution × AMOLED display, 2,500-yard detection range, and a whopping 11-hour battery life, thanks to a backpack battery that clips right to the top of the unit. Adding to its value and versatility, the Krypton2 doubles as a thermal imaging device when paired with Pulsar’s monocular.

One of the arguments for clip-ons is their relatively clear image. Because they use the magnification of the slave scope to enlarge the digital image, they’re largely free of the extreme pixelization that occurs when most thermals zoom in. The Krypton2 has a fixed 3-power magnification, obviously more than the 1X of most clip-ons, which gives it a bit more reach while still delivering a clean, crisp image.

Pulsar ships the Krypton2 with a whole series of adapters to fit a wide variety of rifle scopes. It connects to the very good Stream Vision 2 app that allows users to remotely control the device, stream video from the clip-on, and easily record and share photos and videos. Significantly, it also allows users to upload photos and video to a Stream Vision cloud storage.

Operationally, we had no quibbles with the short, light, durable unit. It has all the functionalities you’d expect – eight color palettes, intuitive arrangement of buttons that are easy to reach from the front of the scope, and 16 GB onboard image storage. But the Pulsar also has the ability to calibrate the unit’s display so it centers in your rifle scope’s exit pupil, a key feature to align the thermal with the daylight optic.

We do have a quibble with Pulsar’s naming convention, though. Would-be buyers should be aware of the significant differences between the Krypton2 FXG50, which we tested, and the FXQ35, which has a lower-resolution sensor and decreased operating range.

Thermal optics are expensive, and there’s no way to avoid paying for performance. But you can choose how much your thermal does. For example, you can spend $4,000 on a thermal scope, but it will only be useful as a weapon sight. On the other hand, you can spend $4,000 on a Rico Micro, and you’ll have a scope, clip-on, hand-held monocular, and a helmet-mounted monocular all in one unit. That’s a pretty compelling feature set, especially if you want one thermal optic that can do it all. 

I tested the Rico Micro on a South Texas hog hunt where I spent most of my time high rack hunting. That meant fast shooting at moving pigs from 30 to 200 yards. I mounted the Rico Micro in front of a Vortex Razor 1-10 set on 1x and pre-adjusted my focus for 50 yards. After an hour riding around, and blasting a few skunks, we spotted a group of bigs a touch over 100 yards away. They were moving left to right, trying to get up and over a hill. I threw the scope to my eye and had a nice wide field of view. Then, I caught the pigs at the edge of the scope and panned left to get on one. I squeezed off two quick shots and heard a loud squeal.

One of the key challenges to the place I was hunting was the large number of exotics and other animals we weren’t allowed to shoot. This made target identification a big deal and I needed to quickly focus the thermal on a running animal, identify it, and then make a shot at it. The Rico Micro’s strength isn’t quick focusing or high-detail at long distances, so it left me wanting a dedicated thermal scope in that scenario. But let’s say I were hunting a feeder, the Rico Micro would be an amazing option for turning a day optic into a night optic. I did find the focus easier to manage when the Rico Micro was used as handheld, especially inside 50 yards.

After hunting with the Rico Micro, I think it’s an excellent option for someone who wants a quality monocular that can also be used as a clip-on or scope for close-range (inside 100 yards) hunting.

ATN ThOR5 LRF

• Mounts on standard 30mm rings
• Excellent built-in rangefinder
• Traditional scope mounting geometry
• Cant indicator
• Robust 3-year warranty
• At about $3,200, a fair value

Cons

• Onboard photo/video storage
• Frustrating menu navigation
• Unreliable app connectivity

Score Card

• Ease of Set-Up: Good
• Connectivity: Poor
• Thermal Performance: Very Good
• Shootability: Very Good
• Field-Worthiness: Fair
• Price/Value: Very Good

Key Features

• 640×480-microbolometer thermal sensor
• ×768-pixel display resolution
• 4-32x magnification
• 9-hour battery life
• Built-in laser rangefinder with 1,000-yard range
• Integrated ballistic calculator
• 8-pattern reticle plus ability to create reticles

You’re going to need to set aside a chunk of time to unlock all the features of this remarkable thermal scope. That’s because there are so many functions and sub-functions, but also because the user interface is frustratingly Byzantine.

The payoff for navigating the convoluted menu is unlocking the abundant capabilities one of the most versatile thermal scopes on the market. The ThOR (not a typo, that’s how ATN names its flagship thermal) has one of the most precise and useful integrated laser rangefinder in the field. But it also has features like manual pixel healer to improve the displayed image, an integrated ballistics calculator, a cant indicator, compass header, wind indicator, and through an available app, the ability to create and share reticles with other users.

ATN is one of the OGs of the thermal market, and early generations were defined by glitchy operation. That’s still an issue with this fifth-generation ThOR, but it’s much more stable than previous iterations. The 4-32×50 model that we tested costs $3,295, pretty good for its boost in sensor resolution. Our model has a 640×480 processor; pay attention since ATN also sells a ThOR 5 with a 320×240 sensor that doesn’t have nearly the resolution or the reach of the more powerful thermal.

You’ll need your own set of 30mm rings to mount the ATN. While many brands are shipping quick-detach rail mounts with their sights, the ability to use your own rings gives users more mounting options. Field tests confirmed the laser rangefinder’s reach to 1,000 yards, and combined with the ballistics function, we made shots out past 500 yards with a variety of calibers.

The ThOR 5 has some significant shortcomings. First, it stores video and photo content on an onboard micro SD card. If you want to share images, you have to manually download the data. While ATN has a fairly robust mobile app — and after working our way through the tedious WiFi connection — we found that it doesn’t yet have the ThOR 5 profile available for linkage. We expect that to change in the coming months.

Users must also manually input important components of ballistics, including altitude, temperature, humidity, and barometric pressure. More advanced thermals fetch that environmental data from onboard sensors. 

Our final gripe is with the 7-button navigation. It takes some time to learn the functions of each button, and in a controlled environment we got pretty good with riffing through menu options and selecting various functions. But in the field, while wearing gloves and in the hectic moment of incoming coyotes, the buttons are too small and closely configured to operate effectively. At one point, while trying to laze a coyote, switch color palettes, and increase magnification simultaneously, we were pushing and releasing buttons like frenzied trumpet players.

But if the interface is frustrating, the capabilitiesof this scope are impressive. The ability to mount it to a rifle, zero it in just a couple shots, then engage targets out to the very limits of its recognition range make it a relatively affordable thermal sight worth a hard look.

How We Tested the Best Thermal Scopes

We tested this year’s class of thermals in the places and style that most American hunters use them: in Texas hunting coyotes, bobcats, and wild hogs.

We based our test out of a sprawling ranch in South Texas’s brush country, where we had thousands of acres of coyote and bobcat hunting out the back door. We also had access to a shooting range with steel targets out to a mile and reaction targets from MR Targets.

We strapped all thermal weapon sights onto either Horizon Firearms bolt guns or ARs chambered in 22 Creedmoor and zeroed the thermals at the range in both daylight and after dark. We used the thermal viewers to assess hits, just as a range spotter might do with daylight optics. And we used the stationary targets as the basis for assessing thermal image, sensitivity, focus, and operating range.

But the bulk of our testing was in the field. Test team member, competitive coyote hunter, and captain of “Team Dead On,” David Stroud, provided his high-rack rig with three swiveling shooting tables. While Stroud drove and called, the rest of the team rotated through sessions on the high rack and with various thermal sights and viewers. In quiet moments between calling sessions, we cycled through thermals’ menus, practiced navigating their buttons and features in the dark, and assessed image quality, various features like rangefinders and color palettes, and recorded videos and photos through the devices.

And we killed coyotes and bobcats, enough to confirm the talents of many of the submissions in real-world conditions. Our plan was to take the collection of thermals to a neighboring ranch for a night of pig hunting, but while we were in South Texas, a monsoonal rainstorm broke the region’s drought, and we were washed out of pig hunting. But Stroud later took many of the thermals to a hog lease, where he finished evaluations and content collection.

In daylight, we further evaluated the units, rating them on ease of use, connectivity to a mobile app, versatility for a wide range of uses, thermal features, image resolution and overall image quality, and durability. And we assessed their value, asking of each submission: how much performance do you get for the money. This particular category, considering thermals can cost several thousand dollars, is among testers’ (and buyers’) most important considerations.

The unit with the highest overall score wins our Editor’s Choice as the best submission in the category. The thermal with the highest Price/Value score wins our Great Buy award.

The Outdoor Life Thermal Test Team

This year’s Outdoor Life thermal test team includes a pair of Texans who handle more thermals in a month than most of us do in a year and three Outdoor Life editors who evaluate gear with a combination of objectivity and close attention to detail and value to readers.

Texan David Stroud actively participates in the growing competitive coyote circuit, hunting all night across Texas at least a couple weekends a month and using a wide variety of thermal viewers and weapon-mounted sights in his pursuit of fur and prize money.

Derrick Ratliff is the founder and president of Horizon Firearms in Bryan, Texas. Ratliff was an early adopter and manufacturer of the 22 Creedmoor, a round that’s become a darling of night hunters for its flat trajectory, mild recoil, and hard-hitting performance on predators and hogs. We ran Horizon’s bolt guns chambered in 22 Creed, fueled by Hornady’s 80-grain ELD-X ammunition.

Alex Robinson is Outdoor Life’s editor in chief and frequent member of OL’s gun and optics tests. He’s an avid deer, turkey, and waterfowl hunter and is relatively new to hunting with thermals.

Scott Einsmann is Outdoor Life’s gear editor, and oversees all of OL’s flagship gear tests. As the youngest member of the test, he’s also a digital native, an important consideration for navigating thermal devices.

Andrew McKean is Outdoor Life’s optics editor and designed our test methodology as well as handling most of the testing logistics.

Things to Consider Before Buying a Thermal Scope

The first thing you should consider if you’re in the market for one of the best thermal scopes is how you’ll use it. Do you want a rifle-mounted scope, with reticle and even a built-in laser rangefinder? If that’s the case, then you’re looking at a fairly expensive subset of thermals. Or maybe you just want a unit to see into the night. A hand-held thermal will do just fine, at a fraction of the cost of the thermal scopes, but without any ability to place after-hour shots.

Second, consider your budget. You can spend anywhere from about $1,000 to well over $10,000 on these devices. But if you’re simply interested in a viewer to detect animals or maybe a car parked at a trailhead, you won’t need all the bells and whistles of a scope. But if you want a plug-and-play scope to shoot coyotes or varmints after legal shooting light, then you should expect to pay well over $3,000 for the most capable rifle-mounted sights.

FAQs

Q: How much do thermal units cost?

Thermal units range in price from around $1,000 for basic thermal viewers to over $7,000 for the most sophisticated rangefinding scopes. Keep in mind that these aren’t night-vision units, which can cost only a few hundred dollars. Thermal scopes depend on a rare-earth element called germanium, which supplies temperature-sensitive glass for thermal units. Generally speaking, the best combination of attributes, capability, and overall utility of thermal units will set you back around $3,000.

Q: What do sensor and display resolution numbers really mean?

That’s a great question. You’ll generally see a couple of different resolution equations mentioned for thermal devices. One measures the sensitivity of the sensor, or the interface that receives the thermal image. The bigger the numbers, the more detail the sensor is receiving. That’s generally a function of quality components and size of the objective lens. For higher-quality units, look for sensor resolution of about 640×480 pixels. You also want to pay attention to the display sensitivity. That’s a measurement of how much detail you’ll see on the screen of the device. The higher the number, the more contrast and detail you’ll observe. Resolution of ×748 provides very good visibility.

Q: What’s the best brand of thermal sight?

There are a number of quality brands on the market, but generally European brands only have thermal sights or what are called clip-on units, intended to be used with a standard riflescope. Units from Russia and Southeastern Europe generally have a good combination of rangefinding riflescopes and hand-helds, though quality is variable. Then there are American brands such as Trijicon and Burris that have consumer versions of their military-grade thermals.

Q: Can I hunt with a thermal scope?

Generally, thermal scopes and viewers are illegal to use in pursuit of game animals, like deer or turkeys. But most states allow their use for non-game animals, like coyotes or raccoons. You’ll have to check with your state’s hunting regulations to see if they’re expressly prohibited. Because they occupy a gray area, it’s a good idea to also check with your local game warden.

Final Thoughts on the Best Thermal Scopes

The best thermal scopes and clip ons are getting more affordable and accessible by the day. Until you are able to see through the darkness and pick up thermal signatures several hundred yards out in the field, you might not think you need one of these devices. But once they reveal all the hidden secrets of the night, you’ll want one just to see what happens around you in the dark.

But not all thermals are created equally. Generally speaking, you get what you pay for, with the cheaper units lacking some crucial attributes, but the most expensive having more modes and capabilities than most people normally need.

For many years, thermal imaging was a myth, and only a select few knew its existence. Now it is publicly available and popular in various fields of activity. On this basis, many devices are created that open up new opportunities for a person. With their help, it is possible to see in the dark and perform many tasks of varying complexity. Modern models of such optics have become less expensive than their predecessors. This circumstance opened up access to thermal imaging for everyone and made purchasing models with optimal characteristics and the necessary set of functions possible. The most demanded product from this category of optics is thermal scopes (TS). It is these devices that we will talk about in our guide.

How does thermal scope work?

Various military operations, night hunting, and dozens of other events held at night would be inaccessible without modern thermal scopes. These devices can uniquely form a thermal image of the examined area, which people use to detect and identify animals, people, various equipment, and surrounding objects. Thanks to this, the user receives valuable information, which he uses to achieve his goals. Despite their popularity, thermal scopes are relatively simple devices. At the same time, simplicity can be traced in everything, including the principle of action.

The work of thermal scopes begins with collecting infrared radiation from all the objects surrounding the user. This work is done by the lens of optics, which is one of the critical elements of the design. Based on the received information, a thermal image is created. To do this, infrared rays are focused and fall on particular detectors. The latter always has a high sensitivity, so they do not let through even the most subtle radiation. These design details help the sight form the so-called thermogram. After that, it is transformed into electrical impulses sent to the electronic system of optics. There they are subjected to various influences, which makes it possible to obtain a thermal image visible to a person at the output. It is sent to the sight display, often built into the eyepiece. The final shot makes it possible to see the boundaries of various objects and the degree of heating of their areas. The higher the temperature, the brighter the color will be. Strongly heated regions are distinguished by warm shades (for example, red, orange, and various variations of yellow), and less hot areas are characterized by cold ones (green, blue, and others).

When do you need a thermal scope for your rifle?

TI technology has many applications. At the same time, in a situation with sights that support this technology, the choice of operating options is significantly narrowed. This is due to the specifics of such optics and their relevance only in certain situations.

The primary users of thermal scopes are military personnel. They actively use these optics while working out interactions between soldiers, simulating combat operations, and searching for enemy soldiers and military equipment. Naturally, in war, such optics become an indispensable assistant. Due to the ability to trap heat through various obstacles, such sights will be most helpful in fog and during dust storms or heavy smoke. They will become just as effective without lighting when the classic NVD fails to form a bright and clear image.

TS often becomes an element of police equipment. Thanks to the abilities of optics, law enforcement officers quickly find hidden criminals at night and eliminate terrorists with sniper shots. The efficiency of such devices must be high, regardless of the surrounding conditions (for example, in bad weather). In some cases, scopes will be great helpers for security guards. They will allow timely identification of the violator and, if necessary, neutralize him.

Another use case is night hunting. This popular pastime bears little resemblance to classic daytime hunting and therefore gives hunters unforgettable emotions. Thanks to the combination of scope capabilities and TI technology, detecting even well-hidden animals and accurately determining their species quickly is possible. Also, these optics will help you aim better and avoid inaccurate shots.

TS rifles are also available to wildlife defenders. They take them while bypassing the protected area to detect unauthorized persons (poachers). In addition, such optics make it possible to accurately shoot tranquilizer darts at night, thereby quickly putting large animals that need human help to sleep.

Thermal or night vision scope – which is better for you?

Since the advent of thermal scopes, users have fiercely debated how effective this optic is and whether it can compete with similar night vision models. It is impossible to make a 100% choice in favor of one of the technologies. Each will show itself better under certain circumstances and help people cope with their tasks.

If the main criterion for the buyer is cost, then TS is inferior to NV optics. The price difference has recently become much smaller, but it still exists. In connection with this feature of the devices, people with limited finances should choose night vision. If large sums of money are allocated to purchase night optics, thermal imaging models will remain a priority. Some design features and lower performance in all situations explain the lower price of NV sights. If there is a lack of illumination, the NV scope will not be able to create a good image, but thermal models will give the expected result even in dense fog, heavy snow, or rain. The picture will be more precise, even with heavy smoke or the operation of thermal optics in places with a high probability of sandstorms.

Almost all thermal scopes models will be a good option for the warm season. At the same time, NV optics will be an excellent assistant in severe frosts. Both types of sights will become equally effective for the transitional spring and autumn periods. Another essential criterion one can choose in favor of a particular technology is the peculiarity of the territory where night optics are operated. In open areas, both TI devices and NVDs will perform well. However, the latter will only be helpful in places with dense vegetation. Under such circumstances, using thermal scopes would be the ideal solution. This optic will allow you to see through foliage and tree branches, making any hidden or camouflaged objects visible.

NV models work ideally only in the presence of lighting (for example, emitted by various celestial bodies). However, they will become useless in dense thickets in caves and similar places on a cloudy nights. TS will be able to form an image in any light. Even without light, the heat map will be as clear and accurate as possible.

From the preceding, NVDs will be a good option in some conditions and others - TS. In this regard, it is recommended to buy both types of optics. Together they will provide the user with excellent visibility at night under all environmental conditions.

Best AGM thermal rifle scopes

Thermal scopes from AGM are ideal for all possible applications of this optic. They combine high quality, excellent ergonomics, reliability, and performance under external conditions. The secret of such success lies in the details. To achieve it, AGM makes exceptional efforts and spends many resources. The result is thermal scopes that, by all criteria, are ahead of similar optics of competitors. Among the many manufactured devices, special attention should be paid to several of the most successful models that have become popular with customers and received positive feedback.

AGM PYTHON TS50-336

This thermal scope is one of the leaders in terms of popularity. It is ideal for hunting and other night activities. The device has an ergonomic design. Its body is made of a special aluminum alloy, which is of excellent quality and is often used in the aviation industry. This material is resistant to various mechanical stresses and copes well with the strong recoil during firing from large-caliber rifles. In addition, it is lightweight, which positively affects the entire structure's mass. The case of AGM PYTHON TS50-336 is completely sealed. Thanks to this feature, the sight can be safely operated even in extreme conditions without fear of dirt, dust, or moisture getting on internal parts.

This scope is elementary to use. At the same time, it has many settings, which makes it possible to adapt the optics to any operating conditions. Each owner of such a TS has access to manual adjustment of the eyepiece and objective and the freedom to choose a reticle from the many available options and several color palettes. It becomes even easier to control the sight with a wireless remote control that easily connects to the device. AGM PYTHON TS50-336 also has an external Wi-Fi module, which makes its possibilities almost limitless. As a power source, two ordinary CR123A batteries are used. Their energy is enough for nearly 8 hours of continuous use of optics. An alternative option would be to operate the device from any external power source connected via a micro USB cable. In this case, the number of hours of battery life available in stock will be even more significant.

Specs to look for when choosing a thermal scope

Modern thermal scopes cost $-$. To save them, it is recommended to responsibly approach the process of choosing optics. Finding the most suitable model to meet the requirements and effectively cope with any job will be possible. When buying a TS, you should consider all the basic parameters that determine the capabilities of optics. It would be best to view additional options to make the device as versatile as possible and expand its scope.

Key parameters considered during selection:

1. Magnification. It is from this indicator that it depends on how close you can visually approach the observed object. All night optics produced today have optimal magnification, depending on many related factors. However, in most cases, 4x-5x optical and 6x-8x digital zoom are considered ideal. There are TS and twice the performance. However, these values are achieved at the cost of resolution, which decreases with increasing magnification. This inevitably leads to a deterioration in image quality. Also, excessively high magnification narrows the field of view, creating specific difficulties for the user during observation, aiming, and shooting.
2. Resolution. Many TS owners consider this parameter to be critical. The image's quality and the device's cost directly depend on it. Before looking for optimal values, you need to know that the result obtained is influenced by the scope's resolution and a similar parameter of the temperature sensor. In this regard, you must not forget about both values and take them into account when buying a particular model. Considering TS with different indicators, it is easy to conclude that the difference between the capabilities of optics will not be so significant. Therefore, it is recommended to purchase models with average performance. They will be moderately priced and will be able to produce a good-quality heat map. Without financial restrictions, you can choose according to your preferences.
3. Range. An essential characteristic of any TS is its range. It shows from what distance the user can quickly identify the target he is observing (the heat emanating from the object will be captured). The simplest models are distinguished by a range of - meters. Middle-class devices have indicators of - meters, and premium ones - - meters. The choice of one of the options depends not only on your financial capabilities but also on the tasks that require TS. If it is important to shoot at targets located at a short distance accurately, then inexpensive sights can be dispensed with. Buying higher-status models with an increased range is recommended to hit distant targets.
4. Grid view. A specific type of reticle ensures high shooting accuracy in each case. Some are ideal for dynamic shooting, others for calmer shooting, and others for maximum accuracy (simplifying the process of making adjustments). Given this feature, choosing a particular option based on current needs is recommended. In the case of the TS, it would be ideal to select the reticle yourself. The most popular variations must be programmed in the purchased model to do this.
5. Refresh rate. This setting should be considered by users who intend to use the TS to observe dynamic scenes (for example, fast-running animals on a hunt). The higher the frequency, the more precise the image will be. For modern models, this characteristic varies between 7.5-60 Hz. Smaller values are suitable for aiming at slow-moving and static targets and larger ones for fast-moving targets. The most commonly encountered devices are 30-40 Hz, optimal for shooters operating the TS for many purposes.
6. Zoom type. To date, TS uses two types of zoom - digital and optical. The first magnifies objects visually with the help of special software, and the second - thanks to the unique characteristics of the lens. Both options are in demand, so choosing one should be a headache exclusively for the buyer. Models with digital zoom cost less but do not guarantee the same good picture quality as devices with optical zoom.
7. Autonomy. People who will operate the TS continuously pay attention to this characteristic for several hours. Most modern models have a battery life of 4-8 hours. Batteries used can be removable or non-removable. The first ones are a priority, as they enable replacing a discharged battery with a new one and continuing to use the sight. However, non-removable batteries are better protected from moisture and other external factors, which reduces energy loss and increases battery life.
8. Cost. When choosing thermal scopes, you should never forget their price. It varies over an extensive range and depends on dozens of factors. Buying the cheapest models and using them for simple tasks (for example, hunting large animals from a short distance) is advisable. More expensive devices, including the most complex assignments, are suitable for any purpose. The critical components of the price are the quality of the optics, the set of characteristics, and the width of the functionality. All this determines the capabilities of TS and their effectiveness when working in certain conditions.
9. Weight and dimensions. Modern thermal scopes are compact and as light as possible. Despite this, there are still specific differences in size and weight, which can be significant for users. It is advisable to use the most compact models on small rifles. They will harmoniously complement the weapon and not overload its barrel with their weight. Standard rifles can be safely combined with almost any modern thermal scopes. In addition, both considered parameters affect the user's sensations after pressing the trigger. Therefore, it is recommended to experimentally choose an option to be as comfortable as possible to shoot even at the most challenging targets.
10. Duration of the warranty period. Many buyers need to pay attention to this indicator, which is less important than other parameters. It reflects the degree of reliability and durability of the optics. The longer the warranty period is, the more likely the thermal scopes you buy will work for several years without breakdowns or any failures.

Thermal imager accessories

All thermal scopes are sold as standard. It may not be enough for some buyers, so various accessories will come to the rescue in this case. All of them will help improve the device's efficiency and the operation's safety and expand the user experience. You can find options perfect for rifle scopes among the many thermal imager accessories.

Most popular accessories:

1. Cases for various purposes. A protective case is one of the essential accessories every thermal scope owner should have. Depending on the material of manufacture, it may be intended for carrying, storing, or transporting optics. In the first case, a simple fabric cover is often used to protect the sight from contact with other parts of the equipment, metal elements of clothing, and other items. Such a cover is always made of a material that does not allow moisture to pass through. Thanks to this, it can be used even in bad weather. The transport case is usually of rigid construction. It provides for a substantial fixation of the optics, thanks to which any of its movements and contacts arising from road irregularities (during transportation in a car), careless handling of personal belongings, and other things will be excluded. Buying a case that will reliably protect thermal scopes from dust is recommended for storage. To do this, it must have a sealed housing made of durable material, which will additionally cover the optics from changes in humidity in the room.
2. Mounts for weapons. Using unique props to install thermal scopes on a rifle without problems. Generally accepted standards produce all of them but often have unique features. The latter adapts the support to a specific thermal scopes model, making mounting it on a weapon as simple as possible. Most often, such accessories are made of durable and at the same time lightweight materials (for example, aluminum or alloys based on it). This ensures the reliability of fixing the optics and avoids excessive weighting of the entire structure. In most cases, the fasteners are all-metal construction that withstands shock loads well and is not afraid of other external influences.
3. Rangefinder. This helpful accessory is a must-have for thermal scopes owners who need to know the exact distance to the target. For modern models of optics, it is recommended to choose laser-type rangefinders. They measure the distance to the target as accurately as possible and do their job well even in the presence of certain obstacles (for example, snowfall, rain, fog). Most rangefinders compatible with thermal scopes are compact and lightweight devices. They are made in a metal case that withstands shock and protects the internal parts of the structure from moisture or dust. Also, most of the models are equipped with an OLED display, which clearly shows the results of the measurements. All rangefinders have their characteristics, so you must choose favor of a particular model.
4. Video encoder. This accessory is a device designed to convert video content into digital format for streaming with the possibility of subsequent saving to any removable media. With this add-on, owners of thermal scopes can record their actions and analyze them after the shooting is completed. The created videos will become a source of important information that will make it possible to make certain adjustments and improve the efficiency of thermal scopes. In addition, the resulting videos can be used to create training video tutorials that help beginners quickly master the operation of such optics.
5. Remote control. This accessory is far from being the most demanded, but its usefulness in some cases cannot be underestimated. This device best suits hunters who want to change the settings of the thermal scope while still watching animals. Most remotes connect to the area using Bluetooth. This option is optimal since all actions (button presses) are instantly transmitted to the optics. 3-6 buttons and a scroll wheel can be used for control. All these elements are configured for specific commands that the user can set. Modern remote controls for thermal scopes are made from lightweight materials. Their case is reliably protected from moisture and dust, making it suitable for outdoor use. Special fasteners are often installed on its surface, allowing you to fix the remote control on the rifle’s forearm or the user's wrist.
6. Sources of additional energy. If you plan to use thermal scopes for a long time, you will need some extra energy sources. It can be a universal power bank to connect a weapon sight using a standard USB cable. This will make it possible to use the optics for more than 10 hours and not monitor the amount of remaining charge. Spare batteries can be an alternative to a power bank. These accessories should only be purchased if the thermal scope has removable batteries. In both cases, it will be possible to maximize the battery life of the optics and wait for the return to places where it is possible to recharge all devices.
7. Interchangeable lenses and eyepieces. You can use interchangeable eyepieces and lenses to adapt your thermal scope to different tasks. They are available in dozens of variations so everyone can find the right accessory. In some cases, it may be necessary to use special adapters to help install lenses and eyepieces on your thermal scope. However, the best option is still to use suitable accessories for the existing optics model.
8. Thermal targets. These unusual accessories are designed for zeroing in on the thermal scope. With their help, doing such work will be much easier and faster. Most of the thermal targets produced are equipped with a multi-line reticle. This makes it possible to zero in the optics more accurately, thereby reducing the number of inaccurate shots in the future. The most popular are thermal targets of the passive type. They can function without using various power sources, which is very convenient and practical. Such accessories use the heat from the environment, based on which a contrast image is formed. As a result, the target will be visible through the thermal scope as a cold object against the background of warmer objects surrounding the user.

F.A.Q.

Why buy a thermal scope when you have an ordinary night vision scope?

An ordinary NV sight can only work effectively with at least some lighting. It is advisable to use thermal scope if it is absent or insufficient for optics operation. It will create a thermal image on the display, on which various objects and objects of the environment will be visible. In addition, TS will be able to make most of the masked and hidden objects visible, which the classic NVD cannot give the user.

What determines the quality of the resulting image?

First of all, the quality of the image depends on the characteristics and capabilities of the sight itself. The better the various indicators are, the more precise the final result will be. Also, the quality is affected by the operating conditions of the optics. Some defects may appear in the picture due to various natural obstacles (for example, rain or snow).

Under what conditions will TS work most efficiently?

The more significant the temperature difference between cold and hot objects, the more efficient TS will work. Such conditions can be obtained on a cold winter night. At higher air temperatures, so-called thermal noise will appear in the image, which will slightly reduce the quality of the result. A similar effect will be observed during the operation of optics during daylight hours.

What can't the thermal scope see?

Thermal imaging can detect heat through various obstacles. However, there are some obstacles that it will not cope with. These include thick walls, solid objects, and glass. In addition, TS may not notice a person in places where the ambient temperature will be approximately equal to the temperature of the human body.

How to choose the right TS?

To choose TS, you need to carefully study the characteristics of the proposed devices and pay attention to their functionality. Researching customer reviews and expert opinions and watching video reviews of specific models are also recommended. It is essential to remember to evaluate your financial capabilities in advance. This will help narrow the search and reduce the time spent choosing suitable optics.

Conclusion

Buying a thermal imaging sight for a rifle is always a difficult and responsible task.
