I get this question at every trade show: "Marc, if I'm buying one thermal, should it be the scope or the handheld?" Wrong question. The best thermal scanner for coyote hunting isn't a backup scope you point at brush before you point a rifle at it. It's a separate tool with a separate job — find the dog, read what it's doing, decide if it's worth calling in. Your rifle scope answers a different question: can I make the shot. Mix those two jobs into one device and you're either carrying a heavy rifle around like binoculars, or you're glassing through a scope with a reticle in your eye the whole time, which is a bad habit that gets worse the longer you do it.
A handheld thermal monocular is the scanning half of a coyote hunting system — it covers ground fast, keeps your rifle off your target until you're ready to shoot, and it's the tool you'll actually hold up for the twenty minutes between calls. The ATN BlazeTrek 6 640 1.75-14x is our pick for coyote work: a 640x512 sensor, sub-18mK sensitivity, and a body light enough to glass with all night.

Why the Latest Generation Stands Out
Gen 6 monoculars didn't get better by adding gimmicks. They got better because ATN put a real thermal sensor — the same 12μm VOx core family used in our rifle scopes — into a body built to be held, not mounted. The BlazeTrek 6 line runs a ≤18mK NETD rating, which is the number that actually matters for scanning: it's the sensor's ability to tell a coyote's body heat apart from a slightly warmer patch of dirt or a sun-baked fence post. Lower NETD means fewer false positives, which means less time chasing hot rocks and more time watching real movement.
SharpIR processing sharpens edges in real time, so a coyote at 400 yards reads as a coyote-shaped heat signature instead of a blur. Six color palettes — White Hot, Black Hot, Iron Red, Alarm, Green Hot, Sepia — let you match the palette to the ground: White Hot for open snow, Black Hot for warm dirt roads holding the day's heat. Add Wi-Fi streaming to the ATN 6 Connect app and a partner in the truck can watch the same feed you're seeing, which matters more on a coyote stand than people give it credit for.

Best Overall: ATN BlazeTrek 6 640 1.75-14x
This is the one I hand to guys who ask me what to buy first. The 640x512 sensor at 12μm pixel size with ≤18mK NETD gives you a detection range of 1000 m — plenty of runway to pick up a coyote working a fence line before it ever knows you're there.
Image Quality
A 640x512 sensor at this price point isn't standard across the category — a lot of handhelds in this range top out at 384x288, which is fine for "something's out there" but weak for "that's a coyote, not a deer fawn or a loose dog." The extra resolution earns its keep specifically at the moment you're deciding whether to call your buddy over or let it walk. SharpIR keeps edges defined instead of smeared, even at the far end of that 1000 m window.
Range and Magnification
1.5-12x optical zoom with 1x/2x/4x/8x digital zoom on top gets you from "wide scan across a field" to "confirm ears and tail" without swapping devices. On coyote stands, most of your work happens at 1x-4x — you're sweeping, not staring through max zoom, because max zoom on a handheld shrinks your field of view to the point you'll miss movement at the edges.
Battery and Build
0.7 lb / 320 g, and it fits in a jacket pocket. That matters more than people think. A coyote stand is a lot of standing still with a monocular in one hand — anything heavier and your arm gives out before the coyotes show up. Rated IP67 and built for -30°C to 55°C, so a January stand in the wind isn't a gear risk. Battery runs about 6.5 hours, which covers a full night set with the internal rechargeable pack, and it charges over USB-C if you're running power from a truck battery bank between stands.
Smart Features
32GB of onboard storage records video and stills so you can review a stalk afterward — useful for figuring out where a coyote hung up out of range and adjusting your next setup. Wi-Fi hotspot pairs to the ATN 6 Connect app for live view on a phone or tablet, which turns a solo scan into a two-person job without a second monocular.
Buy this if you're scanning open pasture, cut fields, or ag ground where a coyote can be 400+ yards out before it's a threat to your set. Skip it if you're hunting tight timber under 200 yards where the 384 sensor variant saves you money without costing you detections.
Best for the Money: ATN BlazeTrek 6 384
Same chassis, same SharpIR processing, same six palettes — the difference is a 384x288 sensor instead of 640x512. For hunters working smaller parcels or calling into brush lines under 300 yards, that's not a real loss. You still detect a coyote well past the range you'd shoot it at; you're just not paying for resolution you won't use on tight ground.
Where It Falls Short
Open country changes the math. Past 500 yards, the lower pixel count starts blurring the line between "heat signature" and "coyote," and you'll find yourself digital-zooming into mush trying to confirm what you're looking at. If you hunt big CRP fields or river-bottom ag ground, spend the extra money on the 640.
Buy this if your ground is under 300 yards edge to edge. Skip it if you're regularly scanning half-mile fields.
Best Lightweight Option: ATN BlazeTrek 6 640
Same 640x512 sensor as our overall pick, minus the extended 14x total zoom range — this variant tops out at 1.5-12x optical. If you already know you'll spend most of your time scanning at low magnification and sweeping wide, that's a fair trade for a marginally lighter, marginally simpler control layout.
Why It's Worth Considering
The honest truth: most coyote scanning happens at 1x to 4x, not at max zoom. You're sweeping a field edge or a fence line looking for movement, not staring at one spot. Buying the extra zoom range on the 1.75-14x model is worth it if you also glass long, open pasture where you need to confirm a target at distance before committing to a stalk. If your ground is tighter, this variant saves you a step in the menu without giving up sensor quality.
Buy this if you want the 640 sensor without paying for magnification range you won't use on tighter ground. Skip it if you regularly need to confirm targets past 600 yards, where the extra zoom on the 1.75-14x model earns its keep.
How to Choose a Thermal Scanner for Coyote Hunting
Match sensor to your ground, not your budget. A 640 sensor is wasted money on a 40-acre parcel boxed in by timber. It's essential on open plains where a coyote can hang up 600 yards out and never commit. Walk your actual hunting ground before you decide.
Weight is a real spec, not a footnote. You'll hold this thing up for longer stretches than you hold your rifle. A half-pound difference between two monoculars matters after the third stand of the night.
Detection range on the spec sheet isn't identification range. A device can "detect" a heat blob well past where you can positively call it a coyote versus a house cat or a deer. Buy enough sensor and magnification that your identification range covers your actual shooting distance, not just your rifle's.
Battery life should outlast your stand plan, not your patience. If you're running four stands a night at 45 minutes each, you need a monocular that clears three hours minimum without a swap, and a way to top it off between stands.
How a Scanner Fits Into the Rest of Your Setup
A monocular isn't the whole system — it's the first step. I run mine in three stages on every stand: scan wide with the monocular the moment I get set up, keep it up during the calling sequence to watch how a coyote approaches, then only shoulder the rifle once I've confirmed a target and a clean shot lane. That order matters. Skip the scan step and you're calling blind, hoping something shows up in your scope's narrow field of view. Skip the "watch the approach" step and you lose the read on whether a coyote is committing or about to bolt.
Snow changes how you use a scanner more than people expect. Fresh snow with clear skies gives you the best contrast you'll get all season — a coyote's heat signature practically glows against a cold, uniform white field, and White Hot palette makes that obvious at a glance. Warm, bare dirt roads or gravel that held the day's heat can throw a false read if you're on Black Hot, since the ground itself glows almost as bright as an animal. Switch palettes as your terrain changes through the night, not just once at the start of your sit.
Wind matters for scanning technique too, not just scent control. On a windy night, coyotes move faster and lower, and you'll catch less "stand and stare" behavior through the monocular. Sweep more often, in shorter passes, rather than holding on one spot — a fast-moving coyote crosses your field of view quickly, and you want to catch the motion, not just the eventual stop.
FAQ
What's the best thermal scanner for coyote hunting?
For most hunters, a 640x512 handheld like the ATN BlazeTrek 6 640 1.75-14x is the best balance of detection range, weight, and price. It's built specifically for handheld scanning, not scope duty, so you keep your rifle down until you've confirmed a target.
Do I need a thermal scanner if I already have a thermal scope?
Yes, if you're serious about coyotes. A scope means pointing a rifle at everything you look at, which is slower and less safe than scanning with a dedicated handheld first, then shouldering the rifle only once you've confirmed a target.
What resolution thermal monocular do I need for coyote hunting?
384x288 covers most calling setups under 300 yards. Step up to 640x512 if you're hunting open fields or ag ground where coyotes hang up at longer distances before committing.
How far can a thermal monocular detect a coyote?
The ATN BlazeTrek 6 640 1.75-14x is rated to a 1000 m detection range, though positive identification of a coyote-sized target happens well inside that number, especially with digital zoom engaged.
Is a heavier thermal monocular worth it for better image quality?
Not usually. The BlazeTrek 6 640 weighs 0.7 lb and still delivers 640x512 resolution with SharpIR processing — you're not trading weight for image quality with the current generation of sensors.
Can I stream my thermal monocular to a phone while hunting?
Yes. The BlazeTrek 6 series has built-in Wi-Fi that connects to the ATN 6 Connect app, letting a second person view your live feed on a phone or tablet, which is useful for two-person calling setups.
White Hot or Black Hot for coyote hunting?
It depends on your background. White Hot tends to stand out best against cold, uniform ground like snow. Black Hot can be easier on the eyes for extended scanning against warmer, uneven terrain like dirt or stubble fields.
Bottom Line
Stop asking your rifle scope to do a scanner's job. The ATN BlazeTrek 6 640 1.75-14x is built to be held up for an hour at a time, sweep wide ground fast, and hand you a confirmed target before you ever mount a rifle. That's the whole point of a dedicated scanner — it's not a smaller scope, it's a different tool for a different half of the hunt.
