Pulsar Thermion 2 LRF XP50 Pro
The Pulsar Thermion 2 LRF XP50 Pro is a 640×480, 17 µm thermal riflescope behind a 50 mm lens, with a built-in laser rangefinder. On the Johnson yardstick that is an estimated 735 m detection and 184 m recognition range for a standing person; Pulsar quotes 1,800 m detection. The box figure is 2.4× the Johnson estimate — a narrower gap than most of the 60 claims recorded here.

Box claim vs. what the optics support
One pixel of this unit sees 0.340 mrad (17 µm ÷ 50 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.340) × 1000 = 735 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.
- 640×480 core — 2.8× the pixels of a 384-class unit
- Publishes its NETD (<25 mK) — 16 units here do not
- Built-in laser rangefinder feeding a ballistic calculator
- Removable battery pack — a spare in the pocket doubles the run time
- 8.5 h published run time, 18th-longest of 64 here
- IPX7 sealed — survives immersion, not just rain
- Records video and streams to a phone over Wi-Fi
- 37 oz — 6th-heaviest of the 36 riflescopes here
- NETD published only as a ceiling (<25 mK), not a measured figure
- 37 oz, above the 27.5 oz median for riflescopes here
- 8× top end is digital — everything past 2× is interpolated pixels
