This is the thermal to buy when you want the sharpest identification of the three, and it is the one to anchor a serious night-hunting rig. Its edge is the 384x288 sensor paired with a sub-20 mK NETD rating, the highest sensitivity AGM offers, so warm bodies separate cleanly from a cool background and you can tell a hog from a stump farther out than the 256-resolution picks allow. The 35mm germanium lens and 3x base magnification give real reach (AGM rates detection to 1800 yards), and it ships complete with a custom ADM quick-detach mount that returns to zero, two rechargeable batteries good for 11 hours, a charger and a case. Add 10 reticles, multiple caliber zero profiles, shot-activated recording and a Wi-Fi app, and it is the do-it-all pick. The AGM RattlerV2 series is featured in Outdoor Life's 2024 Best Budget Thermal Scopes guide (this higher-magnification model is recommended for predator hunters; the guide's Editor's Pick went to a lower-tier sibling).
Pros
- 384x288 resolution with a sub-20 mK NETD rating, the highest sensitivity in the Rattler line, for the clearest target identification of the three picks
- A 35mm germanium lens and 3x base magnification give real reach, with AGM-rated detection out to 1800 yards
- Ships complete: a custom ADM quick-detach mount that returns to zero, two rechargeable batteries (11 hours), a charger and a carry case
- 10 reticle options with multiple caliber zero profiles, shot-activated recording and a Wi-Fi app for a phone
Cons
- At $1,795 it is the most expensive pick here, the trade for the 384 sensor and higher magnification
- Magnification above the 3x base is digital zoom, so the image softens as you zoom in, as with all scopes in this class
- The proprietary lithium-ion battery has no AA or CR123 fallback, so you carry spares rather than buying cells in the field
- The 3x base magnification gives a narrower field of view than the 19-256, so it is a shooter first and a wide scanner second
Best for: predator and hog hunters who want the sharpest 384-resolution identification at higher magnification for shots out to a few hundred yards at night. Scanner-only buyers or the tightest budgets should drop to the 25-256 or 19-256.

“The AGM rattler v2 is a very nice scope for the money. I had been looking at several different options and decided on the rattler v2 because of the options it has, the convenience of the large buttons on top, and the price range. I like this scope so much I will definitely be purchasing another one for my next setup.”

This is the best value in thermal right now, and the pick most night hunters should start with. For under $1,000 you get a 256x192 sensor, a 50 Hz refresh rate (double the 25 Hz of the original Rattler it replaces) and a 25mm germanium lens, which owners consistently find is plenty for hogs and coyotes inside 200 to 300 yards. Owners call it a "working man's thermal": it comes with two rechargeable batteries for 11.5 hours, a quick-detach mount that holds zero, and a simple five-button layout that even a first-timer runs effortlessly. It carries 33 reviews at 4.8 stars, more than the 384 model, a strong signal of real-world satisfaction. It is the value default: enough thermal to hunt seriously without crossing $1,000.
Pros
- Under $1,000 with a 256x192 sensor and a 50 Hz refresh rate, double the 25 Hz of the original Rattler it replaces
- Owners repeatedly call it a "working man's thermal", easy to run for beginners and proven on hogs and coyotes inside 200 to 300 yards
- Two rechargeable batteries (11.5 hours), a quick-detach mount that holds zero, and a case are all in the box
- The most-reviewed pick here at 4.8/5 across 33 owners, plus 10 reticles, zero profiles and a Wi-Fi app
Cons
- The 256x192 sensor gets grainy as you climb past the 3.5x base into digital zoom, an honest owner note
- The 3.5x base magnification is a little high for walking and scanning, where the wider 19-256 is easier
- Not built for long-range night work; owners keep shots inside about 300 yards
- A proprietary rechargeable battery, so you carry spares rather than buying cells in the field
Best for: the best value entry into thermal for night hog and coyote hunting inside about 300 yards, and for beginners or a buddy scope. Step up to the 35-384 for sharper identification and reach, or save with the 19-256.

This is the cheapest honest way into thermal, and the best dedicated scanner or buddy scope of the three. It shares the 256x192 sensor and 50 Hz refresh of the 25-256 but drops to a 19mm lens and a lower 2.5x base magnification, which buys the widest field of view here (49 feet at 100 yards), exactly what you want for sweeping a field to find heat before you shoulder a magnified scope. Owners rate its image quality as good as or better than an ATN Thor 4 and praise it for never glitching, and it still ships with two rechargeable batteries, a quick-detach mount and an IP67 weather rating, at 1.06 lb the lightest pick. Be realistic about the range: the small lens and 256 sensor mean detail fades past about 150 yards, so treat it as a close-range and scanning tool, not a long-shot optic.
Pros
- The lowest price here at $795, the honest entry point into thermal
- The widest field of view of the three (49 feet at 100 yards) and the lowest 2.5x base magnification, so it is the best scanner and buddy scope
- Owners rate its image as good as or better than an ATN Thor 4 and praise it for never glitching
- Two rechargeable batteries, a quick-detach mount and an IP67 weather rating; at 1.06 lb the lightest pick
Cons
- The 19mm lens and 256x192 sensor limit usable range; owners report detail fading past about 150 yards
- Best for close-range and scanning, not long-range night shooting
- Magnification above 2.5x is digital zoom, so it softens as you zoom in
- Thinner stock (8 units showing at gather) than the 25-256 and 35-384
Best for: a first thermal on a budget, a dedicated scanner, or a buddy scope for close-range hog and varmint work inside about 150 yards. Step up to the 25-256 or 35-384 for more reach and identification.

“This is a nice entry level thermal scope. It has high screen resolution, good refresh rate. It has as good or better image quality as a Thor 4. It has never glitched. Return to zero mount and all accessories are included in a nice carry case. It is no wonder these are some of the highest rated thermals for entry level units.”

Premium step-up: ATN Thor LTV 5-15x Gen 5
If you want a different brand and a higher-resolution 320x240 sensor, the ATN Thor LTV 5-15x Gen 5 (list $1,995, about $1,649) is the natural step up from the AGM picks. It is the lightest scope in ATN\'s Thor line, runs a 60 Hz refresh rate, records video to a microSD card and mounts with standard 30mm rings, and owners rate it 4.5 stars across 31 reviews for night hog and coyote work. One honest caveat on availability: unlike the three AGM picks above, the ATN\'s OpticsPlanet product page shows "Check Product Availability" rather than a live in-stock count, so confirm the current stock and lead time on the product page before you order.
How to choose a thermal scope
A few things matter more than the headline magnification number:
- Sensor resolution. 256x192 detects and identifies game inside about 300 yards; 384x288 resolves finer detail and reaches farther. It is the single biggest driver of image quality and price.
- Sensitivity (NETD). A lower mK number means the sensor separates small temperature differences better, so warm animals pop from a cool background. The 35-384\'s sub-20 mK is the sharpest here.
- Base magnification and field of view. A lower base power (the 19-256\'s 2.5x) gives a wider view for scanning; a higher base (the 35-384\'s 3x) trades width for reach. Digital zoom above the base always softens the image.
- Batteries and mount. All three AGM picks include two rechargeable batteries and a quick-detach mount that returns to zero, which saves you buying them separately.

FAQ
What is the best budget thermal scope?
The AGM RattlerV2 25-256 25mm (about $995) is the best budget thermal scope for most night hunters. Under $1,000 it gives a 256x192 sensor, a 50 Hz refresh rate and detection of hogs and coyotes inside 200 to 300 yards, ships with two rechargeable batteries and a quick-detach mount, and carries 4.8 stars from 33 owners. If you want to spend even less, the RattlerV2 19-256 ($795) is the entry point and the best scanner; step up to the 35-384 ($1,795) for a sharper 384-resolution image.
How much does a good thermal scope cost?
A genuinely usable thermal rifle scope starts around $795, a strong value pick lands near $995 to $1,000, and a sharper 384-resolution optic sits around $1,795, which is where our three picks fall. Premium thermals from ATN, Pulsar and others run from about $1,650 well past $5,000, buying higher resolution, longer detection and rangefinders. For night hog and predator hunting inside a few hundred yards, the $800 to $1,800 band covers most hunters.
What thermal resolution do you need for hunting?
A 256x192 sensor, as in the RattlerV2 19-256 and 25-256, is enough to detect and identify hogs and coyotes inside roughly 200 to 300 yards, which covers most night hunting. A 384x288 sensor, as in the RattlerV2 35-384, resolves finer detail and lets you identify targets farther out, so it is worth the extra cost if you shoot at longer range or want the clearest possible image. Higher resolution and a lower NETD (sensitivity) number both improve how cleanly a warm animal separates from the background.
Can you hunt coyotes and hogs with these thermal scopes?
Yes, and that is exactly what owners use them for. Verified owners report taking hogs and coyotes with all three picks, typically inside 200 to 300 yards, with the 384-resolution 35-384 reaching a little farther and the wide-field 19-256 working best as a close-range and scanning tool. Thermal shows an animal's heat signature in total darkness, so it outperforms night vision for detecting game in the dark. Always confirm night-hunting and thermal-optic regulations for your state and species before you hunt.
