A coyote coming to a call does not walk. It commits, hesitates, circles downwind, and then closes the last hundred yards in a dead sprint before it hangs up just out of range. I have sat behind more calling stands than I can count, and the single biggest reason hunters miss that window is not skill — it is glass that cannot find the dog fast enough. The best thermal scope for coyote hunting has to do two things most optics never get right at the same time: paint a wide enough picture that you catch the coyote the instant it breaks cover, and hold enough resolution at magnification that you can put the reticle on a moving target with confidence. This guide ranks the scopes that do both, using the ThOR 6 platform we build for exactly this kind of work.
For calling coyotes, we rank thermal scopes by how fast they get you from "something moved" to a confirmed, aimed shot — not by spec sheets alone. The ATN ThOR 6 640 2-16x tops the list for its wide field of view and 3100 m detection range, with four other ThOR 6 models covering long-range, lightweight, and budget scenarios below.
Quick answer: best thermal scopes for coyote hunting

Why the latest generation stands out for coyote calling
Coyote calling is a game of seconds, and older thermal sensors were built for scanning, not for reacting. The 6th Gen sensor core in the ThOR 6 line runs a ≤15mK NETD on a 12μm pixel pitch, which means the dog separates from the brush and the fence line the moment it moves, not three seconds later when it is already in your lap or already gone. SharpIR AI-image enhancement sharpens edges and contrast in real time, so a coyote slipping through CRP grass or crossing a shadow line still reads as a coyote and not a smear of gray.
The part that matters most for a calling stand specifically is field of view. A narrow tube shows you a tight, bright circle — great for identifying a bedded hog at 400 yards, less useful when a coyote can enter your shot window from any direction and needs to be found in under two seconds. The 640 2-16x has a 12.52° horizontal field of view, close to the widest in the family, which is why it leads this list. Hot Point Tracking backs that up by flagging the hottest signature in the frame automatically, and Picture-in-Picture lets you stay zoomed for a clean shot while still watching the wider field for a second coyote working in behind the first.

Best overall for calling coyotes: ATN ThOR 6 640 2-16x
This is the scope I would put on a rifle for a night of calling, no hedging. It gives you the widest look at the field of anything in the ThOR 6 line at this price point, and that width is what turns a coyote you almost missed into a clean shot.
Field of view and speed on a running dog
At 2-16x with a 12.52° × 9.41° field of view, the 640 2-16x keeps enough of the field in frame that a coyote crossing at a hard run stays inside your glass instead of running out of it. Digital focus responds instantly, so you are not chasing focus while the dog closes distance.
Image quality and detection range
The 640×512 sensor at ≤15mK NETD and 3100 m detection range means you are identifying "coyote" and not just "warm shape" well before it commits to the call. SharpIR keeps edges defined even when the animal is moving through cover, which is where cheaper glass turns a coyote into a blur.
Smart features that matter at a stand
Zeroing Freeze locks the frame so you can true up the reticle without rushing, Picture-in-Picture keeps a wide view active while you are zoomed on the shot, and Recoil Activated Video grabs the last ten seconds before and after the shot automatically — useful when you want to confirm the hit without taking your eye off the field.
Buy this if you call coyotes over open or mixed terrain and need to find and track a fast-moving animal across a wide field. Skip it if your shots are consistently past 500 yards and you want a built-in rangefinder — look at the LRF model below instead.
Best long-range: ATN ThOR 6 LRF 640 2-16x
Same 640×512 sensor, same ≤15mK NETD, same 2-16x range — plus a laser rangefinder and ballistic calculator built into the housing. When a dog hangs up at the edge of your comfort zone instead of committing all the way in, this is the version that gets you a confirmed range and a corrected hold in the same breath.
Laser rangefinder and ballistic calculator
The built-in LRF reads out to 1000 m with ±1 m accuracy, and the ballistic calculator stores up to six profiles so you can swap rifles or loads without re-zeroing. On a coyote that stalls at 300+ yards and won't take another step, that instant range-to-hold is the difference between a shot and a guess.
Detection and battery life
Detection range holds at 3100 m and battery life stays at roughly 9 hours off the same dual 18650 setup as the standard 640, so you are not trading endurance for the added rangefinding hardware.
Buy this if your calling ground has long sightlines and dogs regularly hang up past 300 yards. Skip it if you are calling tight cover or field edges where shots rarely stretch past 150 yards — the standard 640 2-16x does the job for less.
Best lightweight: ATN ThOR 6 Mini 384 2.5-20x
Calling coyotes often means moving — new stand every 20 to 30 minutes, different wind, different setup. Carrying a full-size 640 on your back all night adds up. The Mini 384 answers that with a magnesium alloy housing that weighs in under 500 grams.
Weight and handling
At 1.16 lbs and a 180×65×65 mm footprint, this scope disappears on a lightweight predator rifle. The 3-button control layout stays usable with gloves on, which matters when you are working a stand in January.
Image quality for the size
The 384×288 sensor at ≤18mK NETD and a 2300 m detection range is not the flagship number, but it is more than enough resolution to identify a coyote well inside typical calling distances, and the 0.49-inch 1920×1080 OLED display keeps the image sharp at magnification.
Buy this if you hike multiple stands in a night and want the lightest glass that still performs. Skip it if you need the longest possible detection range or the extra battery runtime of the full-size housing.
Best for the money and most affordable: ATN ThOR 6 384 3.5-28x
This is the scope I point budget-conscious callers toward, because it does not cut the sensor sensitivity to hit a lower price — it cuts resolution and widens the magnification range instead, and for a lot of coyote setups that trade makes sense.
NETD and detection at this price
You still get the ≤15mK NETD from the 6th Gen sensor core, just on a 384×288 array instead of 640×512. Detection range comes in at 2750 m, which covers realistic coyote engagement distances with room to spare.
Narrower field of view tradeoff
The 3.5-28x magnification range starts higher than the 640 2-16x, which means a narrower field of view at the low end — 7.53° × 5.65° versus 12.52° × 9.41°. On a coyote that is running hard and close, that narrower window is the real cost of the lower price. If most of your calling happens in tight cover where shots are close and fast, weigh that tradeoff before you buy.
Buy this if your calling distances run consistent and you want ThOR 6 sensitivity at the lowest entry price. Skip it if you call wide open pasture where a coyote can appear from any direction and you need the widest possible field of view.
How to choose a thermal scope for coyote hunting
Start with your terrain, not the spec sheet. If you call from a fence line into open pasture or crop stubble, field of view matters more than raw magnification — a coyote can come from any of 180 degrees and you need to find it fast, which favors the 640 2-16x's wider glass over a narrower high-power option. If you call from a stand tucked into brush or timber where the shot window is a lane rather than a field, a narrower field of view and higher base magnification, like the 384 3.5-28x, works fine because you already know roughly where the shot will present.
Distance is the next question. Most coyote calling happens inside 200 yards, but ranch and open-country callers regularly work dogs at 300 to 500 yards, where a hang-up is common. If that describes your ground, the built-in laser rangefinder and ballistic calculator on the LRF model earns its keep — guessing range on a moving coyote at distance is how misses happen.
Weight matters more than most hunters admit until they have carried a full-size scope through a cold night of stand-hopping. If you are covering ground on foot between calls, the Mini's sub-500-gram housing will save your neck and your patience without giving up the sensor tech that makes the sighting in the first place.
Budget last, and honestly. Every scope on this list runs the same 6th Gen sensor sensitivity — the difference is resolution, field of view, and features like the rangefinder, not image quality at the core. Buy the field of view and detection range your terrain actually demands, not the biggest number on the page.
FAQ
What is the best thermal scope for coyote hunting?
For most callers, the ATN ThOR 6 640 2-16x is the best overall choice because its wide field of view and 3100 m detection range make it fast to find a coyote breaking cover at a call. Hunters shooting long, open ground should consider the LRF version instead.
Do I need a wide field of view or high magnification for coyote hunting?
Wide field of view matters more for calling, since a coyote can appear from any direction and close distance fast. High magnification helps more for identifying and placing a shot at longer, known distances, which is why terrain and typical engagement range should drive the choice.
Is a thermal scope or night vision scope better for coyote hunting?
Thermal detects heat signatures directly, so it finds a coyote through brush, fog, or total darkness without any ambient or infrared light. Night vision amplifies existing or IR light instead, which works but generally detects a moving coyote later and at a shorter range than thermal.
What detection range do I actually need for coyote hunting?
Most calling setups play out inside 200 yards, so any of the ThOR 6 models here, with detection ranges from 2300 to 3100 meters, cover that with margin. The extra range matters most for open-country callers who need to spot a dog approaching from far off before it commits.
What is the most affordable thermal scope for coyote hunting in the ThOR 6 line?
The ATN ThOR 6 384 3.5-28x is the entry point into the platform, keeping the same ≤15mK NETD sensitivity as the flagship 640 while stepping down sensor resolution and detection range to hit a lower price.
Does a built-in laser rangefinder matter for coyote calling?
It matters most when dogs regularly hang up past 200 to 300 yards, since an instant, accurate range paired with a ballistic calculator removes the guesswork on a moving target. For close, tight-cover calling, it is less critical and the standard model is a reasonable place to save money.
How much does battery life matter for an all-night calling setup?
A lot, if you are running multiple stands over several hours. The full-size ThOR 6 models run roughly 9 hours on dual 18650 batteries, while the Mini runs closer to 7 hours on a single battery — plan spares accordingly for a long night.
Final take
Coyote calling rewards the hunter who finds the dog first, and that comes down to field of view and sensor speed more than any other spec on the page. The ATN ThOR 6 640 2-16x is built for that exact moment — wide enough to catch the commit, sharp enough to hold the shot when the dog closes distance fast. If your ground calls for more range or less weight, the LRF and Mini variants cover those cases without stepping outside the same sensor platform.
