THERMAL MONOCULARS
Find the heat.
One hand,
any hour.
A thermal monocular is the fastest, most affordable way into thermal — and the first tool out of the bag after dark. Sweep the country and warm-bodied game lights up through grass, shadow and total darkness. Genuine stock, backed here in Australia by C.R. Kennedy.
Three handhelds — how much reach do you need?
The short version — the Mile 2 is the value carry-everywhere scanner; the Arc LRF adds a rangefinder for shots at distance; the Sirius steps up to a sharper 640/HD sensor and the longest reach for hunters who want the most capable handheld.
All three find warm game in total darkness. What changes is detail, distance, and whether you want to range — each step up buys you more of all three. Here's how to choose.
How a thermal monocular works — and how to choose one
New to thermal? Start here.
A thermal monocular doesn't amplify light the way night vision does — it reads heat. Every living animal radiates infrared heat, and the sensor turns that into a clear image, so it works in total darkness and by day. A warm pig, fox or deer glows against the cooler background, straight through long grass, shadow and light scrub that hides it from the naked eye.
Three numbers do most of the work. Sensor resolution — 256×192, 384×288 or 640×512 — sets how much detail you see; a higher-resolution sensor resolves a clearer, more identifiable shape at distance. NETD, in millikelvin, is thermal sensitivity, where a lower number is better — it reads finer temperature differences and holds the picture together in fog, rain and humidity. And the lens — 15 to 50 mm — sets your reach.
If you need to know how far away an animal is — for a shot, or a stalk — choose a model with a built-in laser rangefinder (LRF), like the Arc LRF. A monocular is a detection tool, not an aiming device: you use it to find and range game, then engage with your rifle and its own scope. For many hunters it's the first thermal they ever buy.
Scan with the monocular, shoot with the scope
A handheld finds and ranges fast and wide; a riflescope takes the shot. Most serious hunters run one of each — and the Arc LRF hands your scope the exact distance before you shoulder it.
