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.

Riflescope1280-classLaser rangefinder

The ATN ThOR 5 XD LRF 4-40x is a 1280×1024, 12 µm thermal riflescope behind a 100 mm lens, with a built-in laser rangefinder. On the Johnson yardstick that is an estimated 2,083 m detection and 521 m recognition range for a standing person; ATN quotes 3,660 m detection (human (ATN 'Human Detection Range', 4000 yd)). It is the heaviest of the 36 riflescopes here, at 52.6 oz.

Claim ÷ estimate

1.8×

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

One pixel of this unit sees 0.120 mrad (12 µm ÷ 100 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.120) × 1000 = 2,083 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

1280-class core — 4.0× the pixels of a 640×512
12 µm pitch — the 100 mm lens sees what a 17 µm core would need 142 mm to match
60 Hz core — 20 % more frames than the 50 Hz norm when an animal runs
Built-in laser rangefinder feeding a ballistic calculator
10 h published run time, 6th-longest of 64 here
Records video and streams to a phone over Wi-Fi
Detection claim is only 1.8× our estimate — one of the more conservative box figures here
