Thermal & Night Vision
Thermal and night vision optics both let you see after dark, but they work differently. Thermal reads heat, so a hog or coyote glows against cooler ground. Night vision amplifies the light that is there. Use thermal scopes for the rifle, thermal monoculars for scanning, and night vision optics when you need to see detail. ATN, AGM, Pulsar, Nocpix, RIX and Pard lead this shelf.

Thermal vs night vision
A thermal imager builds its picture from heat differences. It does not need any light, sees through darkness the same as through dusk, and makes warm animals obvious against a cool background. It is less good at fine detail: you see a hot shape more than you see fur or a face.
Night vision, whether tube-based or digital, amplifies the small amount of light available (moon, stars, or an infrared illuminator) and shows an image that looks more like a normal scene in green or white. That makes identification easier, but in total darkness without an IR source it struggles. The RIX models on our night vision optics page are Gen2+ white phosphor tubes, and the RIX Tourer T20 is a digital night vision scope.
Fusion devices combine the two. RIX lists a thermal and IIT fusion binocular, and AGM lists the Observir fusion. Fusion sits at the top of the price ladder on this page.
Thermal scopes by resolution
Most of this page is thermal riflescopes, and the first number to look at is sensor resolution. The figure in a name like AGM Rattler V2 35-384 or ATN Thor 6 Mini 3-24x 640 is the horizontal pixel count of the sensor. More pixels means more detail, which helps most when you want to tell a coyote from a fox before you squeeze. We sort them for you:
| Resolution | Who it suits | Shop |
|---|---|---|
| 256 | First thermal, close hog work, tight budgets | 256 thermal scopes |
| 384 | The common middle for hogs and predators in fields | 384 thermal scopes |
| 640 | Sharper image for identification across open ground | 640 thermal scopes |
| 1280 | Top-end detail for serious night hunters | 1280 thermal scopes |
Many names also carry LRF, which means a laser rangefinder is built in. Clip-on units from Sig, Armasight, ATN and Athlon mount in front of a day scope instead of replacing it, so you keep your daytime zero. BA Global Defense even lists a thermal bow sight. Browse all of them on the main thermal scopes page.
Handheld thermal: scan first, then shoot
Experienced night hunters rarely scan a field through the rifle. A handheld thermal monocular does the searching, so the muzzle stays pointed somewhere safe until there is a reason to raise it. Sig's Echo thermal monocular and the RIX Pocket K3 thermal imaging monocular are on this shelf, and ATN lists the Binox 6 640 thermal. Many hunters keep a regular pair of hunting binoculars for the daylight half of the trip.
Power, mounting and the rest of the setup
Thermal and digital optics run on batteries, and cold drains them faster. This page includes spare cells and packs from Pard, Pulsar and Athlon; carry one in an inside pocket. Most thermal riflescopes need rings or a mount sized to their tube, and ATN lists its own dual cantilever 30mm mount here. Our 30mm scope rings and quick detach scope mounts cover most setups; QD mounts let you swap between day and night optics.
Night predator hunting pairs well with an electronic or mouth-blown predator call, a rifle bipod, and a red or green hunting light for walking in without lighting up the whole field.
Rules on hunting with thermal and night vision vary by state, by species and by season. Check with your state wildlife agency before you take any of these into the field.
Thermal & Night Vision FAQs
Is thermal or night vision better for hog hunting?
Thermal is better at finding hogs because body heat stands out in any darkness or cover. Night vision is better at identifying details. Many hog hunters scan with thermal and confirm with whatever gives them the clearest look.
What does 384 or 640 mean on a thermal scope?
It is the sensor's horizontal resolution in pixels. A 640 sensor shows more detail than a 384 at the same magnification.
What is a thermal clip-on?
A thermal unit that mounts in front of your existing day scope. You keep your normal reticle and zero, and add thermal imaging at night.
Can thermal see through glass or walls?
No. Thermal cannot see through ordinary glass or solid walls. It reads surface heat, so heavy brush can also hide an animal.
