Nocpix QUEST H35R
The Nocpix QUEST H35R is a 640×512, 12 µm thermal binocular 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; Nocpix quotes 1,800 m detection (6 ft tall object). Its 5 h published run time is 38th-longest of the 64 units here that publish one.

Box claim vs. what the optics support
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.

Derived here
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.

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.
- 640×512 core — 3.0× 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
- Published NETD of ≤15 mK, 1st-lowest of the 51 units here that publish one
- 60 Hz core — 20 % more frames than the 50 Hz norm when an animal runs
- Built-in laser rangefinder
- Removable battery pack — a spare in the pocket doubles the run time
- IP67 sealed — survives immersion, not just rain
- Rangefinder but no ballistic calculator — the holdover is still yours to work out
- Warranty terms not published
