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.

AGM Rattler V2 25-256

Riflescope256-class

The AGM Rattler V2 25-256 is a 256×192, 12 µm thermal riflescope behind a 25 mm lens. On the Johnson yardstick that is an estimated 521 m detection and 130 m recognition range for a standing person; AGM Global Vision quotes 1,250 m detection (6 ft (1.8 m) object). It is the cheapest of the 36 riflescopes here, at ~$875.

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

One pixel of this unit sees 0.480 mrad (12 µm ÷ 25 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.480) × 1000 = 521 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

12 µm pitch — the 25 mm lens sees what a 17 µm core would need 35 mm to match
Removable battery pack — a spare in the pocket doubles the run time
11.5 h published run time, 2nd-longest of 64 here
17.3 oz — 8th-lightest of the 36 riflescopes here
IP67 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
