A good thermal scope for hunting has to work the way you actually hunt, and that rarely means one animal on one kind of ground. You might sit a field edge waiting on hogs, still-hunt a coyote through timber, then glass a bean field for deer sign, all in the same night. That mix is why we point people first at ATN's 6th-gen ThOR 6 line: the sensor is sharp enough to tell a coyote from a stump across an open field, sensitive enough to pull a bedded hog out of cool brush, and light enough to carry all night. This roundup is organized by how far and where you hunt, so a small hog in close cover and a coyote across the beans both get the right tool. Every pick below detects heat in true darkness, so you are not waiting on the moon.
Best all-around — ATN ThOR 6 640x512 2-16x: the same 640 clarity with a wider low end that shines when a hog steps out of thick cover. The natural fit if your nights mix field edges and timber.
Best value — ATN ThOR 6 384x288 2.5-20x: the lightest here at 1.74 lbs, still carrying the full ThOR 6 feature set. The smart way into 6th-gen thermal for closer-range hog and predator work.
Why ATN's 6th-gen ThOR 6 fits real hunting
ATN's 6th-gen ThOR 6 fits real hunting because it handles the whole night, not one narrow situation. A hunting night throws mixed animals and mixed ranges at you, so the ThOR 6 pairs a high-contrast sensor with NETD under 15 mK to separate a warm animal from cool ground, whether that is a hog in brush or a coyote in a cut field. SharpIR AI cleans up the image so edges stay defined, and Hot Point Tracking marks the warmest object with one tap when you are trying to hold on a mover in clutter. Recoil Activated Video saves the shot automatically, Zeroing Freeze lets you lock and recall a zero fast between hunts, and Picture-in-Picture gives you a zoomed aiming window without losing the wider view. Add Wi-Fi with ATN Connect 6, up to 8x digital zoom, and a Full-HD OLED display, and you have one scope that carries from the truck to last light. Every model below is from this current 6th-gen line only.
ATN ThOR 6 640x512 3-24x - best overall
The ATN ThOR 6 640x512 3-24x is the best overall thermal scope for hunting because it gives you the sharpest image and the longest reach in the line, which pays off most on the ground where game is farthest away. The 640x512 sensor and 50 mm lens push detection out to 3650 m, and NETD under 15 mK keeps a warm animal crisp against a cool field or ridge.
Reach for open fields and long shots
When you glass a wide bean field or a cut pasture, you need to spot game before it drifts off, and this scope's 3650 m detection and 24x top end let you find and study an animal far out. That extra reach means you can tell a lone coyote from a fence post at a distance, decide on it calmly, and set up rather than getting surprised at close range.
Resolution and NETD you can actually see
The 640x512 sensor is like stepping from a standard-definition picture up to full HD: more pixels means you identify an animal, not just spot a warm blob, farther out. NETD under 15 mK is the sensitivity figure, and lower is better, because it separates small heat differences so a bedded hog reads clearly against cool brush. With SharpIR AI cleaning edges and up to 8x digital zoom, detail holds as you magnify in on a target.
Tools that catch the shot
Recoil Activated Video starts recording before you break the shot and saves the clip off recoil, so you catch the whole sequence hands-free and can review a hit or a follow-up later. Hot Point Tracking tags the warmest object with one tap, which helps when a coyote is trotting across the field and you need to keep the mark on it.
Who it's for: the hunter who works open country, wants the sharpest image and the longest reach, and doesn't mind a flagship-tier optic. Who it's not for: someone who only hunts close-cover timber where long detection goes unused, or a strict value build who would rather save weight and cost with a smaller lens.
ATN ThOR 6 640x512 2-16x - best all-around
The ATN ThOR 6 640x512 2-16x is the best all-around thermal scope for hunting because it keeps the 640x512 clarity and the full feature set but starts at a lower 2x magnification with a 35 mm lens. That wider low end is easier to work when a hog steps out of close timber, while 3100 m detection still covers realistic field ranges.
Wide low end for mixed ground
The 2x starting magnification gives you a broad field of view, which is what you want when game appears close and fast at a woods edge. You can find and follow a mover in brush, then zoom in as it settles. Think of it as trading a little top-end reach for quicker target acquisition on the kind of mixed field-and-timber nights most hunters actually have.
Same clarity, everyday reach
The 640x512 sensor and NETD under 15 mK deliver the same high-contrast image as the flagship; you are only giving up the longest detection and top magnification. On the distances a typical hunt lives at, that is a trade most people won't feel. Picture-in-Picture gives you a zoomed aiming box without losing the wide view, and the replaceable 18650 cells keep you hunting with a spare in a pocket.
Who it's for: the hunter who wants 640 clarity and every feature on a do-everything rig that handles field edges and closer cover alike. Who it's not for: a dedicated long-range open-country setup that needs the flagship's extra reach, or a strict value build.
ATN ThOR 6 384x288 2.5-20x - best value
The ATN ThOR 6 384x288 2.5-20x is the best value thermal scope for hunting because it brings the 6th-gen feature set into a hunting build at the entry tier and the lightest weight here, 1.74 lbs. The 384x288 sensor and 25 mm lens still reach 2300 m, plenty for most hog and predator work at closer range.
Full features at the entry tier
You are not stripping out the tools that matter afield. Recoil Activated Video still records off recoil, Zeroing Freeze still gives you a fast re-zero between hunts, and Hot Point Tracking still marks the warmest animal. Six color palettes let you switch between White Hot, Black Hot, and heat-map views to suit the scene and your eyes. What you save is money and a little weight, not core capability.
Where the 384 sensor sits
A 384x288 sensor is a step below 640 in resolution, the way more dots on a screen show finer detail than fewer. You still detect and identify well at typical hunting ranges; you just won't stretch as far or pull as much detail at maximum zoom. NETD under 15 mK keeps the image contrasty, so a warm hog still pops against cool ground even on the value pick.
Who it's for: the hunter getting into 6th-gen thermal who wants the real features without the flagship outlay, on the lightest scope here, mostly at closer range. Who it's not for: someone who regularly reaches long distances across open fields or wants the finest detail at high magnification; step up to a 640 model for that.
How to choose a thermal scope for hunting
Choose a thermal scope for hunting by matching the sensor and reach to the animals and ground you actually hunt, then let weight and features sort the rest. Start honest about your real distances and cover, then decide how much detail and reach you need.
- Resolution — a 640x512 sensor identifies game farther out than a 384; if you glass wide fields, the 640 earns its keep, while a 384 is plenty for closer hog and predator work.
- NETD — thermal sensitivity, where lower is better; NETD under 15 mK keeps the image high-contrast so a warm animal separates cleanly from cool brush, ground, or cover.
- Detection range — be honest about how far you really shoot; detection tells you how far you can spot heat, not identify or ethically take an animal.
- Magnification — a lower start (2x) gives a wide view for close timber; a higher ceiling (24x) helps study game across open country, but too much zoom up close narrows your view.
- Weight — you carry the scope all night, so an ounce or two matters; all three models here sit under two pounds, with the 384 the lightest.
- Battery — roughly nine hours on 18650 cells covers a full night, and replaceable batteries let you swap in a spare instead of ending the hunt.
- Features — Recoil Activated Video, Zeroing Freeze, Hot Point Tracking, and Wi-Fi with ATN Connect 6 make the scope easier to run and let you record and share your hunts.
How we picked these ATN thermal scopes
We judged these against one job: hunting a full, mixed night after hogs, deer, and coyote across fields and timber. Sensor resolution came first, because a 640x512 image identifies game farther out where fields open up, while a 384 handles closer cover well and saves weight. From there we weighed thermal sensitivity (NETD under 15 mK for high-contrast separation), detection range against realistic hunting distances, refresh smoothness for tracking movers, weight on an all-night carry, and roughly nine hours of runtime on 18650 cells. We only looked at ATN's current 6th-gen ThOR 6 line, so nothing here is an older or discontinued model. The honest trade-offs: the flagship 3-24x costs and weighs the most for reach that close-timber hunters rarely use, the 384 gives up resolution and long-range detail, and heavy Wi-Fi streaming can shorten battery life. None of these suits a daylight-only hunter or someone who wants a simple low-power day optic. This is an in-house comparison of ATN's own range, not an independent lab test, so measure the specs against your real ground and game before you buy.
Frequently Asked Questions
What is the best thermal scope for hunting?
The ATN ThOR 6 640x512 3-24x is our best overall pick for hunting. Its 640x512 sensor and NETD under 15 mK read hogs, deer, and coyote cleanly out to 3650 m detection, and at 1.83 lbs it carries well all night. If you hunt more timber than open country, the 640 2-16x gives a wider low end, and the 384 2.5-20x is the lighter value option.
Can a thermal scope see animals in complete darkness?
Yes. A thermal scope reads the heat every animal gives off, so it works in total darkness with no moon and no ambient light at all. That is why the ThOR 6 line lets you spot a hog or coyote by its warmth against cool ground long before your eyes could, whether you are hunting a black-dark field or thick timber.
Do I need a 640 sensor to hunt, or is a 384 enough?
For closer-range hog and predator work, the 384x288 sensor is plenty and it is the lightest, best-value pick here. Step up to a 640x512 sensor if you hunt open fields and want to identify game farther out with more detail at high zoom. The jump from 384 to 640 is like moving from a standard-definition picture to full HD.
How far can these thermal scopes detect game?
Detection ranges run from 2300 m on the 384x288 2.5-20x up to 3650 m on the 640x512 3-24x. Keep in mind detection is how far you can spot heat, not how far you can identify or ethically take an animal, which is always closer. Match the range to how far you truly shoot rather than to the biggest number.
What does Recoil Activated Video do while hunting?
Recoil Activated Video starts recording before you break the shot and saves the clip automatically off the rifle's recoil. That means you capture the whole sequence hands-free, without reaching for a button in the dark, and can review the hit or a follow-up later. It works alongside Wi-Fi and ATN Connect 6 so you can share your hunts.
How long will the battery last on a hunt?
The ThOR 6 models here run about nine hours on two 18650 cells, which covers a typical full night out. Because the batteries are replaceable, you can carry a spare set and swap them in the field rather than ending the hunt early. Heavy Wi-Fi streaming and recording will shorten that runtime, so plan for a spare on long nights.
Which ThOR 6 is best for hogs versus coyotes?
For hogs that often appear close out of cover, the 640 2-16x or the value 384 2.5-20x give a wide, quick field of view. For coyotes across open fields where distance matters, the 640x512 3-24x reaches farthest and pulls the most detail. All three read both animals well; the difference is how much open-country reach you want.
If you hunt hogs, deer, and coyote across fields and timber, start with the sensor and reach that match your real ground, then let weight and features fill in the rest. The ATN ThOR 6 line covers all of it across three tiers, so you can pick the clarity, detection range, and magnification that fit how you actually hunt. Compare the full 6th-gen lineup and specs on the ATN thermal scope collection, then match a model to your fields, your timber, and your distances. Whichever you choose, you get the same core toolset built for a full night in the field.
