Estimated from pixel pitch and lens focal length using the Johnson criteria (2, 8 and 13 pixels across a 0.5 m human critical dimension), clear air, 50 % probability. A model of the optics, not a measurement — real range depends on temperature contrast, humidity and the animal.

Pulsar Axion 2 LRF XG35

Handheld monocular640-classLaser rangefinder

The Pulsar Axion 2 LRF XG35 is a 640×480, 12 µm thermal handheld monocular behind a 35 mm lens, with a built-in laser rangefinder. On the Johnson yardstick that is an estimated 729 m detection and 182 m recognition range for a standing person; Pulsar quotes 1,750 m detection. Its published <40 mK NETD ranks 36th of the 51 units here that publish one.

Claim ÷ estimate

how much further the box reaches than a 2-pixel, 0.5 m criterion

One pixel of this unit sees 0.343 mrad (12 µm ÷ 35 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.343) × 1000 = 729 m. The box figure is usually computed against a person’s 1.8 m height instead, which is why it comes out higher. Full explanation.

What the spec sheet says

Read from the published specifications and this catalog’s own numbers — not from owner reports, which we have not collected for this unit.

For it

640×480 core — 2.8× the pixels of a 384-class unit
12 µm pitch — the 35 mm lens sees what a 17 µm core would need 50 mm to match
Built-in laser rangefinder
Removable battery pack — a spare in the pocket doubles the run time
IPX7 sealed — survives immersion, not just rain
Records video and streams to a phone over Wi-Fi
Detection claim is only 2.4× our estimate — one of the more conservative box figures here
