Pros & cons
Reading thermal monocular specs
Sensor resolution matters most: 256 is a close-range spotter, 384 covers most feeder and field hog hunting, 640 shows real detail past 200 yd, 1024 and 1280 are for open country.
NETD (in mK) is heat sensitivity. Lower is better and gives a cleaner picture in humid or foggy nights.
Lens size sets reach. Small 10–19 mm lenses give a wide view for scanning close; 35–50 mm lenses see farther but narrower.
Detection range is the maker's claim for spotting a man-size heat source, not for telling a hog from a calf. Plan on identifying game at a fraction of it.
A monocular is for scanning, not aiming. Most hog hunters scan with a monocular and shoot with a thermal scope.
How the ratings work
Popularity, image and durability stars are my own judgment from reviews (Outdoor Life's thermal monocular test, last updated 2025; American Rifleman; rifleconfigurator.com's 2026 coverage) and how common each one is with hog hunters. They are a starting point, not lab results.
Sources and limits
Prices are US street prices seen in 2026 at retailers such as EuroOptic, Botach, Cabela's, Kygunco and maker stores. Thermal prices change often and sales are common; check before buying.
Outdoor Life picks and test notes: Nocpix Vista H50R (Editor's Choice), Guide TE211M (Great Buy), Topdon TS004 (best under $400), Pulsar Axion 2 XQ35 Pro LRF, Pulsar Telos LRF XL50, ATN BlazeTrek 325.
ATN figures (BlazeSeeker $569, BlazeTrek 325 $1,195, BlazeHunter XD $4,995) are from rifleconfigurator.com's Gen 6 write-up. Vortex Veil 400 specs are from Vortex dealer listings.
Specs marked "not listed" or "not confirmed" were not checked; a dash means I don't have a reliable number.
Check your state's night-hunting rules. Texas allows hunting feral hogs at night with thermal on private land with landowner permission.
