Thermal & Night Vision for Predators
Check your state's law on night hunting, thermal and night-vision optics and infrared lights first. Then how night vision and thermal imaging differ, scanners vs. weapon sights, specs and safe identification, following Wikipedia and the Alaska Bowhunter Safety Course.
Thermal and night-vision devices can help in predator and feral hog hunting at night, where it is legal. This guide covers the law first, then how the technologies work, what to compare and how to stay safe, following Wikipedia and the Alaska Bowhunter Safety Course. We have not tested devices against one another; the three models compared below are described from their makers’ own product pages, without prices.
Always check the law first
Night hunting rules differ from state to state and sometimes by county. Before you buy anything, confirm with your state wildlife agency:
- Whether night hunting is legal, and for which species and seasons.
- Whether thermal or night-vision optics are allowed, on a firearm or as a hand-held scanner.
- Whether artificial light, including infrared illuminators, is allowed.
- Any permits, landowner requirements, or restrictions near roads and homes.
The Alaska course is plain that ignorance of hunting law is no excuse for breaking it, and that legal methods and equipment are among the laws every hunter must know.
How the two technologies differ (Wikipedia)
- Night vision (image intensification): a night-vision device amplifies the little visible light available and converts near-infrared light into a visible image, typically monochrome green. Passive devices rely on ambient light; active devices add an infrared illuminator.
- Thermal imaging: a thermal camera detects infrared radiation coming from the surfaces of objects, which depends on their temperature and on how well they emit heat, plus radiation reflected from surroundings, and turns it into an image. It works in a different part of the infrared spectrum from night vision.
Scanners vs. weapon-mounted optics
A hand-held scanner or monocular lets you search and identify without pointing a firearm at anything; a weapon-mounted sight is for aiming. Only aim a firearm at something you have already identified as a legal target. Check whether your state allows each type.
What to compare
Look at each maker’s stated detection and identification ranges, resolution, magnification, battery life and weather resistance, and test how clearly a device shows an animal at the distances you hunt.
Night vision scopes and thermal clip-ons compared
A clip-on (front attachment) mounts ahead of the day scope you already have and turns it into a thermal or night sight; a digital day/night scope replaces the day scope altogether.
| Model | Type | From the maker | Links |
|---|---|---|---|
| ATN TICO 6 | Thermal clip-on, also a handheld monocular with an optional eyepiece adapter | Sensor 256x192, 384x288 or 640x512 (12 µm); stated detection range 1,500, 2,710 or 3,500 m by sensor; 50 Hz; quick detach mount included; about 8 hours of battery (4 hours per battery); IP67; 511 g for the 256x192 version | See on Amazon · Maker’s page |
| Pulsar Krypton 2 | Thermal front attachment that doubles as a handheld spotter | FXG50: 640x480 sensor (12 µm), 50 mm lens, stated detection range 2,300 m; FXQ35: 384x288 (17 µm), 35 mm lens, 1,350 m; 50 Hz; HD AMOLED display; Wi-Fi, Bluetooth and a remote included; up to 11 hours on its battery pack; IPX7 | See on Amazon · Maker’s page |
| ATN X-Sight 5 | Digital day and night riflescope | 3-15x or 5-25x; night vision mode; IR850 illuminator included; ballistic calculator; optional built-in laser rangefinder (LRF model) | See on Amazon · Maker’s page |
How we put this together. Two thermal clip-ons and one digital night scope, compared on what each maker states on its own product page, checked on 28 October 2026. We have not used them side by side, and how well a device shows an animal in the dark is not something a spec sheet can show. ATN’s spec table for the X-Sight 5 did not load for us, so we give only what its product description states. Detection range is each maker’s own figure, and seeing a heat source is not the same as identifying an animal (see field safety below). There are no prices here: the Amazon link searches for the exact model, and we may earn a commission if you buy through it. Check that your state allows a thermal or night vision sight on a firearm before you buy.
Field safety at night
The Alaska course’s rules matter even more in the dark: be sure of your target and what’s in front of and beyond it, and shoot only with a safe backstop. A heat signature alone may not tell you what an animal is, or whether a person, pet or livestock is nearby; identify fully before any shot. Leave a hunting plan with someone saying where you’ll be and when you’ll be back.
