Thermal scope hunting is really a game of matching the optic to the quarry and the ground you chase it on. A hog in thick timber, a coyote working a wide pasture, and a scan-and-stalk night on a river bottom all ask different things of a scope — reach here, a wide view there, value everywhere it does not cost you the shot. This roundup sorts three ATN ThOR 6 scopes by the hunt they fit best, from long-range predator work to close timber hogs, so you can pick by the animal and terrain you actually hunt. It leads with the most versatile hunting scope of the three, the ATN ThOR 6 640x512 3-24x.
Best for close-to-mid hunts — ATN ThOR 6 640x512 2-16x: 640 clarity, a wider starting view for cover, and a hot-swap battery for long nights.
Best value hunting pick — ATN ThOR 6 384x288 2.5-20x: the most accessible way in, ideal for shorter-range hogs and predators.
Why ATN's 6th-gen ThOR 6 line fits real hunting
Every scope here is from ATN's current 6th-generation ThOR thermal scope line, tuned for the way hunters actually work. All three read heat, so they find warm game in total darkness, light brush and fog, and all three share a ≤15 mK NETD for a clean, high-contrast picture on the mild nights that trip up lesser optics. Recoil Activated Video captures every shot, Zeroing Freeze locks a clean zero on hard-kicking rifles, and Hot Point Tracking plus a smooth refresh keep a running hog crisp. What separates them is sensor, glass and zoom — so you pick by your game and ground.
ATN ThOR 6 640x512 3-24x — best all-round hunting scope
One scope for timber and open ground
The ATN ThOR 6 640x512 3-24x is the do-everything hunting scope. Its 640x512 sensor resolves fine detail — the standard-to-high-definition jump — so a coyote at the far side of a field reads as a coyote, and the 50 mm lens detects heat to roughly 3,650 m for time to spot and set up. The 3-24x range drops low enough for a brushy timber edge and reaches high enough for a far ag lane on the same outing.
Built for the shot
A ≤15 mK NETD holds the image clean on mild nights, Hot Point Tracking marks a moving animal, and Recoil Activated Video records the shot the moment the rifle fires. This is the pick for a hunter whose ground and game vary week to week.
Who it is for: a hunter who chases different game across mixed terrain and wants one scope for all of it. Who it is not for: a budget buyer or a pure close-timber hunter — the reach outruns that need.
ATN ThOR 6 640x512 2-16x — best for close-to-mid hunts
A wider start for game in cover
The 640x512 2-16x keeps the high-resolution 640 sensor and ≤15 mK NETD but starts at a slightly wider 2x, which helps you pick up a hog moving through cover before you zoom in to confirm. On a 35 mm lens it detects to about 3,100 m — more than enough for the close-to-mid distances most hunts run.
Batteries that last the hunt
Its replaceable 18650 battery system lets you hot-swap fresh cells when a set fades, so a long night of stand-and-scan does not end early. For hunters who put in real hours after dark, that keeps you on the game. A property can go quiet for hours and then come alive all at once, and the last thing you want is the optic quitting just as a sounder finally steps into the field. A pocketful of charged cells and a quick swap means the scope stays ready as long as you are willing to sit.
Who it is for: a hunter working close-to-mid ground who wants 640 clarity and long field time. Who it is not for: a shooter reaching across wide-open country — the 3-24x flagship stretches farther.
ATN ThOR 6 384x288 2.5-20x — best value hunting pick
Full hunting features, value sensor
The 384x288 2.5-20x is the most accessible way into thermal scope hunting and plenty of scope for shorter-range hogs and predators. You still get SharpIR, Recoil Activated Video, Zeroing Freeze, Hot Point Tracking, Wi-Fi with ATN Connect 6 and six color palettes — the value shows only in the 384x288 sensor and the roughly 2,300 m detection range, both ample for timber and pasture-edge hunting.
The lightest to carry
At about 790 g it is the lightest scope here, which a hunter feels on a long walk-in or a night of stalking. The 2.5-20x range still gives the magnification to confirm your target before you commit. On a spot-and-stalk hunt where you cover ground on foot and shoulder the rifle a hundred times before you get a shot, every ounce you shave off the front of the gun is an ounce your arms do not have to fight. For a first thermal or a rig you carry more than you rest, that lighter package is a genuine advantage, not just a spec-sheet footnote.
Who it is for: a value-minded hunter whose shots stay inside a couple hundred yards. Who it is not for: a long-range hunter who needs 640 detail to ID game far out.
How to choose a thermal scope for hunting
Match the scope to your game and ground, then to your longest realistic shot:
- Coyotes and open-field game: go 640x512 with the biggest lens — the 3-24x for reach and clean identification far out.
- Timber hogs and close cover: a wider starting zoom helps; the 640x512 2-16x or the value 384x288 2.5-20x both start wide.
- Long night sessions: favor the replaceable-battery 640x512 2-16x so you can hot-swap cells.
- First thermal / tighter budget: the 384x288 2.5-20x gives the full feature set for less — confirm the scope holds zero on your rifle first (all three ThOR 6 models do).
How we picked these ATN thermal hunting scopes
This is an in-house comparison of ATN's own 6th-generation range, not an independent lab review, so weigh it against your own hunting and check the specs. We ranked the picks the way a hunter would: sensor resolution and NETD for how cleanly game reads at your distances, detection range and magnification against real game-and-ground scenarios, refresh rate for tracking moving hogs and coyotes, and weight and battery for a full night afield. We considered only current ThOR 6 models because older units trail on sensor and processing. Honest trade-offs: the flagship's reach is more than a close-timber hunter needs, and the value 384 gives up fine detail far out. None of these suits a daylight-only shooter or a poorly zeroed rifle — match the scope to your game, your ground and your longest realistic shot.
Frequently Asked Questions
What is the best thermal scope for hunting?
For most hunters the best all-round thermal scope is the ATN ThOR 6 640x512 3-24x. Its 640x512 sensor, ≤15 mK NETD and roughly 3,650 m detection range cover everything from timber hogs to far pasture coyotes on a single optic. If your hunting stays closer or budget matters, the 384x288 2.5-20x is a strong value alternative.
What thermal scope is best for hog hunting specifically?
Hogs move through cover after dark, so a scope that starts at a wider zoom helps you pick them up fast. The ATN ThOR 6 640x512 2-16x starts wide with 640 clarity and hot-swaps batteries for long nights, while the value 384x288 2.5-20x also starts wide for shorter timber shots. Both find hogs in total darkness.
How far can I hunt with these thermal scopes?
Detection range runs from about 2,300 m on the 384x288 2.5-20x to roughly 3,650 m on the 640x512 3-24x. Detection means spotting a heat signature, not fully identifying it, so your ID and shooting distances are shorter. Match the scope to your longest realistic shot rather than to the maximum detection figure.
Do thermal scopes work for daytime hunting too?
Yes. Thermal scopes read heat rather than visible light, so the ATN ThOR 6 works day or night. Many hunters use them around the clock for scanning and shooting. The image shows heat signatures rather than a natural colored view, which is a different look from a day optic but still fully usable in daylight.
Will a thermal scope hold zero on a hunting rifle?
Yes. All three ATN ThOR 6 scopes are recoil-rated for hard-kicking hunting calibers and use Zeroing Freeze to lock a clean zero. Sight the scope in for your rifle and load first, and it will hold that zero shot after shot. Recheck zero if you move the scope between rifles.
Which scope is lightest for a long walk-in?
The ATN ThOR 6 384x288 2.5-20x is the lightest at about 790 g (1.74 lbs), which a hunter notices on a long walk-in or stalk. The two 640 models weigh roughly 830 g (1.83 lbs). Balance that weight against the range and resolution your hunting actually needs.
Whatever you chase and wherever you chase it, the ATN ThOR 6 640x512 3-24x is the one scope that handles timber hogs and far-field coyotes alike. Want a wider view for close cover or a value setup for shorter shots? The 640x512 2-16x and 384x288 2.5-20x cover those hunts. Compare the full ATN ThOR thermal scope lineup, match the sensor and reach to your game and ground, and get sighted in before your next night out.
