Best Thermal Scope for Coyote Hunting in 2027: ATN ThOR 6 Picks by Budget

By Marc Vayn, Founder, Chairman & CMO, ATN Corp — Updated November 2026 · Prices and specs: ATN product pages, checked 5 November 2026

Picking the best thermal scope for coyote hunting comes down to one number most buyers ignore: field of view. A called dog gives you a few seconds between the moment it breaks cover and the moment it wins the wind, and a narrow thermal rifle scope spends those seconds hunting for the animal instead of aiming at it. Five ATN ThOR 6 models cover the range from a $689 carbine optic to a rangefinding 640, and the one you want depends on how far your stands actually reach.

Short answer: for most coyote callers the ATN ThOR 6 640×512 2-16x at $2,295 is the best pick — the widest field of view here at 12.52°, matched only by its own LRF version, and 3,100 m of detection. Take the LRF 640 ($2,595) for long open ground, the Mini 384 ($1,295) for a light carry rifle, and the Mini 256 ($689) if your ceiling is $1,000.

Quick answer: the five picks

• Best overall — ATN ThOR 6 640×512 | 2-16x ($2,295): the most ground in the frame when a dog breaks cover.
• Best long-range — ATN ThOR 6 LRF 640×512 | 2-16x ($2,595): same optic plus a rangefinder for dogs that hang up.
• Best lightweight — ATN ThOR 6 Mini 384×288 | 2.5-20x ($1,295): 528 g for hunters who move stand to stand.
• Best value — ATN ThOR 6 384×288 | 3.5-28x ($1,695): flagship ≤15mK sensitivity and the longest reach per dollar here.
• Best under $1,000 — ATN ThOR 6 Mini 256×192 | 2-16x ($689): cheapest ThOR 6, mounts straight to a Picatinny rail.

Comparison table

Prices and specs: ATN product pages, checked 5 November 2026. These are the current store prices; the list price on each product page is higher. Detection range is published in meters; the yard figure is converted. Detection is the distance at which the optic registers a heat signature, not the distance at which you can tell a coyote from a dog, and not a shooting distance. The three full-size models use 30 mm rings, sold separately; both Mini models ship with a Picatinny mount in the box.

How we picked

I founded ATN in 1995 and we make every scope on this page, so this is a guide to the ThOR 6 line rather than an independent test of the market. That is the disclosure; here is the compensation for it. Every number above comes from our own product pages and specification sheets, checked on the date in the line under the table, which is more than most roundups can say.

The ranking criterion is time from "something moved" to an aimed shot. That puts field of view first, sensor resolution and NETD second, detection range third, then weight, battery and price. I hunt hogs at night with a ThOR on the rifle, not coyotes, so nothing here is written as a field test of calling: the ordering comes from ATN specifications and from what our customers report back about the window a called dog gives them. Where we had no measured data, there is no claim.

Best overall for calling coyotes: ATN ThOR 6 640×512 2-16x

The ThOR 6 640 2-16x wins because it starts at 2× through a 35 mm lens, and that gives a 12.52° × 9.41° field of view — the widest here, shared only with its own LRF version. On a dog coming hard at 80 yards, that is the difference between picking him up in the frame and panning for him.

Specifications: 640×512, 12µm VOx, 50 Hz, ≤15mK NETD; 35 mm F/1.0 germanium lens; 2-16× with 8× digital zoom; field of view 12.52° × 9.41°; detection 3,100 m (3,390 yd); no rangefinder; 0.49-inch 1920×1080 OLED; two 18650 cells, about 9 hours; 830 g / 1.83 lb; 6,000 J recoil rating; IP67; 64 GB storage; 30 mm rings sold separately; $2,295.

Strengths

The widest view here and the flagship ≤15mK sensitivity, which is what separates a coyote from sun-warmed ground late in the evening. Recoil Activated Video keeps the ten seconds before and after the shot, and Zeroing Freeze pauses the image at impact so you can move the reticle without a spotter.

Limitations

No rangefinder and no ballistic calculator — on this model those are the LRF version's job. At 830 g plus 30 mm rings it is a full-size optic, and the rings are not in the box.

Not ideal for

Open country where dogs hang up past 300 yards and you are guessing at the distance: take the LRF version. If your rifle is a light carbine, the Mini 384 saves 302 g.

Best long-range: ATN ThOR 6 LRF 640×512 2-16x

The LRF 640 is the same scope with a laser rangefinder in the objective bell. Past 200 yards your misses stop coming from image quality and start coming from range estimation, and this is the model that removes the guess.

Specifications: identical core to the 640 2-16x — 640×512 at ≤15mK, 35 mm F/1.0 lens, 12.52° × 9.41° field of view, 3,100 m detection, 0.49-inch 1920×1080 OLED, about 9 hours on two 18650 cells. Adds a built-in rangefinder to 1,000 m (1,094 yd) with ±1 m accuracy on an eye-safe Class 1 905 nm laser, and a ballistic calculator storing six profiles. 855 g / 1.89 lb; $2,595.

Strengths

You range the dog and get a corrected aiming point without taking your eye off him. Six ballistic profiles cover more than one rifle, and the laser is eye-safe Class 1.

Limitations

$300 more than the standard 640 and 25 g heavier — the rangefinder module also adds 8 mm of height to the body, which matters for ring clearance on some rails.

Not ideal for

Stands where everything happens inside 150 yards. Buy the standard 640 and put the $300 into calls and ammunition.

Best value: ATN ThOR 6 384×288 3.5-28x

The ThOR 6 384 3.5-28x keeps the flagship ≤15mK sensitivity and trades pixel count and field of view for $600. It is the lowest-priced full-size scope of the five here, and the one to buy if your stands are long and open rather than tight. ATN also builds the same 384 sensor in a 2.5-20× configuration at a lower price with a wider view — see the full ThOR 6 range if neither of the two here fits your ground.

Specifications: 384×288, 12µm VOx, 50 Hz, ≤15mK NETD; 35 mm F/1.0 germanium lens; 3.5-28×; field of view 7.53° × 5.65°; detection 2,750 m (3,007 yd); no rangefinder; 0.49-inch 1920×1080 OLED; two 18650 cells, about 9 hours; 830 g / 1.83 lb; 6,000 J recoil rating; IP67; 30 mm rings sold separately; $1,695.

Strengths

Same ≤15mK NETD as the 640 models, which is the number that decides whether there is a usable picture on a damp night. The highest top magnification of the five at 28×, and 2,750 m of detection — more than the Mini 384 for $400 more.

Limitations

7.53° is the narrowest field of view here, about 60 per cent of the 640's 12.52°. On a close, fast dog you will be panning. The 384×288 array also runs out of detail sooner than a 640 when you push the zoom.

Not ideal for

Thick cover and short lanes, where the whole game is picking the animal up quickly — that is the 640 2-16x or the Mini 256.

Best lightweight: ATN ThOR 6 Mini 384×288 2.5-20x

The Mini 384 is the pick when you walk between stands all night. At 528 g it is 302 g lighter than the full-size models, and the mount is in the box rather than on a separate line of the invoice.

Specifications: 384×288, 12µm, 50 Hz, ≤18mK NETD; 25 mm F/1.0 germanium lens; 2.5-20× with 8× digital zoom; field of view 10.5° × 7.9°; detection 2,300 m (2,515 yd); no rangefinder; 0.49-inch 1920×1080 OLED; one 18650 cell, about 7 hours; 528 g / 1.16 lb; 180×65×65 mm; IP67; Picatinny mount included; 64 GB storage; $1,295.

Strengths

The lightest way here to get a 384 sensor on the rifle, $400 cheaper than the full-size 384 and with a wider field of view than it as well — 10.5° against 7.53°. Same 0.49-inch 1920×1080 display as the flagship, and it clamps straight to a rail.

Limitations

≤18mK instead of ≤15mK: a real difference on humid nights, small but there. Seven hours on a single cell is the shortest runtime of the five, so an all-night sit needs a spare.

Not ideal for

Sitting one stand from dusk to dawn, where the nine-hour dual-battery models earn their weight.

Best under $1,000: ATN ThOR 6 Mini 256×192 2-16x

The Mini 256 at $689 is the cheapest ThOR 6 and the answer to the under-$1,000 question. It is a genuine thermal scope, not a compromise dressed up as one, and its 11.7° field of view is wider than either 384 model here.

Specifications: 256×192, 12µm, 50 Hz, ≤20mK NETD; 15 mm F/1.0 germanium lens; 2-16×; field of view 11.7° × 8.8°; detection 1,200 m (1,312 yd); no rangefinder; 0.32-inch 800×600 OLED; one 18650 cell, about 8 hours; 500 g / 1.10 lb; 180×65×65 mm; 6,000 J recoil rating; IP67; Picatinny mount included; 64 GB storage; $689.

Strengths

Lowest price and lightest body of the five, and it mounts directly to a Picatinny rail — no rings to buy and no ring torque to get wrong. Keeps the 64 GB of storage, Recoil Activated Video, Wi-Fi and the 6,000 J recoil rating of the rest of the line.

Limitations

256×192 carries 49,152 pixels against 327,680 on a 640 sensor, so detail collapses much sooner when you zoom. ≤20mK is the highest NETD here, the display steps down to 0.32-inch 800×600, and 1,200 m is the shortest detection range.

Not ideal for

Anyone who already knows they want to identify a dog past 200 yards. You will buy twice. For a wider look at this price bracket see our guide to the best thermal scope across the line.

What is the best thermal scope for coyote hunting under $1,000?

The ATN ThOR 6 Mini 256×192 2-16x at $689 — it is the only ThOR 6 that clears $1,000 on both the store price and the $985 list price. What you give up against a 640 model is resolution and reach: 256×192 instead of 640×512, ≤20mK instead of ≤15mK, 1,200 m of detection instead of 3,100 m, and a 0.32-inch 800×600 display instead of the 0.49-inch 1920×1080 panel.

What you keep is the part that decides whether you see the dog at all: a 12µm sensor, a 15 mm F/1.0 germanium lens, an 11.7° field of view, IP67 sealing and the same 6,000 J recoil rating. For calling inside 150 yards that is enough scope. The same chassis on a carbine is covered in our guide to the best thermal scope for AR-15.

What magnification do you need for coyote hunting?

Lower than you think. Base magnification and lens size set your field of view together, and on a called dog the field of view is what matters: on the 35 mm lens, 2-16× opens to 12.52° horizontally while 3.5-28× sees 7.53° — about 60 per cent as much ground. At 2× you find the animal, then step the digital zoom up in 1×/2×/4×/8× increments once he stops.

Take the higher base magnification only if your stands are long and open and you are confirming the animal before he commits. Everywhere else the wide end wins, because the clock starts when the dog appears and the scope that was already looking at the right piece of ground wins the shot. The mechanics behind lens size and field of view are in our explainer on lens size and field of view.

Thermal or night vision for coyote hunting: which should you buy?

Thermal wins for finding, night vision wins for identifying under light. A thermal scope reads emitted heat, so it works in complete darkness, light fog and standing grass, and a coyote's body against cool ground is the easiest target thermal gets. Digital night vision amplifies reflected light and needs some light or an IR illuminator, but it shows fur, markings and the shape of the animal the way your eye expects them.

For calling at night, thermal is the right tool: the dog is usually moving, usually partly screened, and you need to find him before you can judge him. The honest limit is that thermal shows you a heat shape, not a coat pattern, so confirming what you are looking at happens closer than the detection numbers suggest. The full comparison is in night vision vs thermal.

How do you set up a thermal scope for coyote hunting?

Four things done before you leave the truck, in this order.

1. Zero it properly. Use a heat source as the target and Zeroing Freeze, which pauses the image at the moment of impact so you can move the reticle onto the hit without a partner calling shots. A heating target ships in the box with every ThOR 6. Step by step: how to sight in a thermal scope.
2. Pick a palette and stay with it. Six are on board — White Hot, Black Hot, Iron Red, Alarm, Green Hot and Sepia. White Hot is the default; Black Hot often reads better once the ground has held the day's heat; Iron Red helps some eyes pick a warm body out of clutter. Switching mid-stand costs you seconds.
3. Calibrate before the first call. Non-Uniformity Correction runs Auto, Semi Auto or Manual. If the image starts showing a faint grid or ghosting, that is NUC asking for a cycle, not a fault — the mechanics are in our piece on the clicking sound and NUC calibration.
4. Set the reticle and the recording. Ten reticle styles with transparency control, and Recoil Activated Video that keeps ten seconds before and after the shot. The clip is how you settle an argument about where the bullet went before you walk up.

How far can you spot a coyote with a thermal scope?

Much farther than you can shoot one, which is why detection numbers mislead. The five scopes here publish detection from 1,200 m on the Mini 256 to 3,100 m on both 640 models — that is the distance at which the sensor registers a heat signature, nothing more. Identifying that the heat signature is a coyote and not a house cat or a calf happens at a fraction of it, and the practical shooting distance is set by your rifle and cartridge long before the optic runs out.

For calling, treat detection as a scanning figure and nothing else. What matters on the stand is how quickly the animal fills enough of the frame for you to judge him, which is a function of base magnification, sensor resolution and NETD together. We unpack how the published figure is produced in our article on thermal scope detection range.

How to choose a thermal scope for coyote hunting

Answer four questions in order and the model picks itself.

1. How far do your stands reach? Inside 150 yards, the Mini 256. Out to 250, the Mini 384. Past 300, a 640 — and past 300 at unknown distances, the LRF version.
2. How thick is your cover? Tight lanes and brush reward a wide base view: 12.52° on the 640 2-16x, 11.7° on the Mini 256. Open pasture is where the 3.5-28× earns its narrower 7.53°.
3. How much weight will you carry? A full-size ThOR 6 is 830 to 855 g before rings. The Minis are 500 to 528 g with a mount included. If you walk more than you sit, that gap decides it.
4. What is your budget, including the mount? The full-size models need 30 mm rings, sold separately; both Minis ship with one. The spread runs from $689 to $2,595.

FAQ

What is the best thermal scope for coyote hunting?

The ATN ThOR 6 640×512 2-16x at $2,295. It pairs the widest field of view here, 12.52° × 9.41°, with a 640×512 sensor at ≤15mK and 3,100 m of detection. If you want the distance read for you, the LRF version at $2,595 is the same optic with a rangefinder.

What is the best thermal scope for coyote hunting under $1,000?

The ATN ThOR 6 Mini 256×192 2-16x at $689, list price $985. It is the only ThOR 6 under $1,000 on both numbers; the 2.5-20× version of the same Mini 256 also lands under $1,000 at the store price if you want more magnification. You trade resolution and reach for the price, but you keep an 11.7° field of view, IP67 sealing and a Picatinny mount in the box.

What is the best thermal scope for the money?

The ATN ThOR 6 384×288 3.5-28x at $1,695. It keeps the flagship ≤15mK NETD and gives the longest detection of the five at 2,750 m, for $600 less than the 640. If field of view matters more to you than reach, the Mini 384 at $1,295 is the better buy.

What magnification scope for coyote hunting?

Start low. On the same 35 mm lens a 2× base gives 12.52° of horizontal view against 7.53° at 3.5×, and on a called dog finding him beats magnifying him. Use the 8× digital zoom in steps once the animal stops.

Can you hunt coyotes at night with a thermal scope?

Technically yes — thermal reads emitted heat and needs no light at all, which is why night calling is where these optics earn their price. Whether you may do it where you hunt is a separate question: night hunting and thermal rules vary by state and sometimes by county, so check with your state wildlife agency first.

Are thermal scopes legal for coyote hunting?

It depends on where you are. Some states allow thermal on coyotes year-round, some restrict it by season, licence or landowner permission, and some prohibit it outright. We cannot answer this for your ground — confirm the current rules with your state wildlife agency before you plan the hunt.

Is a thermal scope or night vision scope better for coyote hunting?

Thermal, for finding. It works in total darkness, light fog and grass, and a warm body against cool ground is the clearest signal thermal produces. Digital night vision shows more recognizable detail on a lit animal, but it needs light or an IR illuminator to work with.

What detection range do I actually need for coyote hunting?

Far less than the spec sheets offer. Most calling plays out inside a few hundred yards, so even the 1,200 m of the Mini 256 is more detection than a typical stand uses. Detection is a scanning number; identification and the shot both happen much closer.

Does a built-in laser rangefinder matter for coyote calling?

It matters once dogs start hanging up outside 200 yards. The ThOR 6 LRF 640 reads to 1,000 m with ±1 m accuracy and feeds a ballistic calculator holding six profiles, so you range and get a corrected aiming point without leaving the eyepiece. Inside 150 yards it is $300 you do not need to spend.

How much does battery life matter for an all-night calling setup?

A lot if you are running several stands. The full-size ThOR 6 models run about 9 hours on two 18650 cells, one internal and one swappable. The Mini 384 runs about 7 hours and the Mini 256 about 8, both on a single cell, so carry a spare or a USB-C power bank.

Final take

If you want one answer and no hedging: put the ThOR 6 640×512 2-16x on the rifle and go call. The wide base view is the thing that converts the few seconds a coyote gives you, and the ≤15mK sensor is what makes him visible against ground that has been in the sun all day. If $2,295 is not this year's number, the Mini 256 at $689 will show you dogs you have been calling past for years, and it will make the case for the 640 better than I can. Compare the full line on our thermal scope page, and zero it properly before the first cold night.
