384×288 12μm VOx Sensor1,200-Yd Heat Detection50Hz OLED EyepieceIP67 Waterproof
Unlike infrared night vision that reflects off brush and spooks game, the pocket-sized Cosari ThermoScout Pro reads pure body heat through fog, brush, and total darkness on a buttery-smooth 50Hz HD OLED display.

Standard night vision needs moon or IR light and gets blinded by tree branches. ThermoScout Pro’s 12μm vanadium oxide (VOx) thermal core detects temperature differences as small as 0.025°C—making bedded deer, coyotes, feral hogs, or trespassers glow like neon against cold timber.
Cheap 9Hz or 25Hz thermal units stutter when you pan across a field. ThermoScout Pro runs at a silky 50 frames per second with one-button switching between White Hot, Black Hot, Red Alert (highlights the warmest spot in bright red), Ironbow, and eye-saving Forest Green.
Weighing just 11.2 oz in an IP67 nitrogen-purged magnesium-alloy shell, it runs for 9 continuous hours on a single USB-C charge and records thermal video onto 32GB of internal memory or streams live to your iPhone/Android.

✓ See What Flashlights & Night Vision Miss: the Cosari ThermoScout Pro requires zero visible or infrared light.

Night vision amplifies ambient moonlight or uses an infrared flashlight that reflects off leaves and spooks animals. A thermal monocular detects pure infrared heat radiation—so it works in 100% pitch darkness, heavy fog, smoke, and even broad daylight to reveal hidden animals.
ThermoScout Pro detects deer-, hog-, or human-sized heat signatures out to 1,200 yards, with clear species recognition inside 450 yards.
Yes! That is one of its most popular uses. Warm downed game and fresh blood trails glow brightly against cool ground and brush, saving hours of grid searching.
Yes. Unlike night-vision tubes that burn out in daylight, thermal sensors work 24/7. You can scan thick daytime timber to spot bedded deer or turkeys that are invisible to binoculars.
Yes. Either connect to the monocular’s built-in WiFi hotspot using the free iOS/Android app to view and download footage wirelessly, or plug the included USB-C cable into any computer.
Yes. It features a soft folding rubber eyecup and a -5 to +5 diopter adjustment ring so you can use it with or without eyeglasses.
You are protected by our 30-day 100% money-back guarantee. Take it into the woods or out on your ranch for 30 nights risk-free.

★★★★★Spotted a sounder of 14 hogs at 650 yards across our peanut field
I’ve used $1,400 Pulsar units and honestly couldn’t believe how clean this $299 Cosari looks. The 50Hz refresh rate has zero lag when scanning tree lines, and Red Alert mode lit up a group of hogs tucked inside a mesquite thicket before they ever stepped into the field.

Shot a 9-pointer right at last light and lost the pinprick blood trail in heavy laurels. Switched on Red Hot mode and saw him glowing 70 yards away.

★★★★★Saves me 45 minutes checking calving heifers every night
Instead of driving the UTV through muddy pastures with a spotlight at 1 a.m., I step out on the back porch, scan our 80 acres with the ThermoScout, and count every cow and calf in 60 seconds.

★★★★★Rides in my patrol bag every night shift
For rural property checks, search-and-rescue calls, and locating suspects hiding in brush lines, this thing punches way above its price class. The hot-spot tracker locks onto a warm footprint or person immediately.

White Hot is super bright, so I love that Cosari included a Forest Green palette that doesn’t dilate your pupil.

★★★★★Bought the 2-pack for our coyote calling rig
One guy scans left, one scans right, and we never have to wave a red or IR light that educates call-shy coyotes. We’ve doubled our stands’ success rate this month.

Bought it for hunting, ended up using it around the house to find where cold air was leaking around our attic hatch and basement rim joists.

★★★★★Remember thermal doesn’t see through glass windows
Just like all thermal optics, roll your truck window down before scanning because glass reflects heat. Out in the open it is crystal clear.

We live on 12 wooded acres and our dog bolted after a rabbit after dark. One sweep with the ThermoScout and he lit up like a lightbulb 200 yards down the ravine.
