Nocpix ACE H50R

Riflescope640-classLaser rangefinder

The Nocpix ACE H50R is a 640×512, 12 µm thermal riflescope 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 2,610 m detection (6 ft tall object). Its published ≤15 mK NETD ranks 1st of the 51 units here that publish one.

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
  • 640×512 core — 3.0× the pixels of a 384-class unit
  • 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 feeding a ballistic calculator
  • Removable battery pack — a spare in the pocket doubles the run time
  • IP67 sealed — survives immersion, not just rain
Against it
  • 39.5 oz — 3rd-heaviest of the 36 riflescopes here
  • 39.5 oz, above the 27.5 oz median for riflescopes here
  • Warranty terms not published
