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.

Nocpix VISTA S50R

Handheld monocular1280-classLaser rangefinder

The Nocpix VISTA S50R is a 1280×1024, 12 µm thermal handheld monocular behind a 50 mm lens, with a built-in laser rangefinder. On the Johnson yardstick that is an estimated 1,042 m detection and 260 m recognition range for a standing person; Nocpix quotes 2,270 m detection (6 ft tall object). It is one of only 3 1280-class units in the catalog.

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

One pixel of this unit sees 0.240 mrad (12 µm ÷ 50 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.240) × 1000 = 1,042 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 50 mm lens sees what a 17 µm core would need 71 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

Against it

Only 4 h published run time
Rangefinder but no ballistic calculator — the holdover is still yours to work out
~$4,499 against a ~$3,000 median for handhelds here
23 oz, above the 18.1 oz median for handhelds here
20× top end is digital — everything past 2× is interpolated pixels
