Pulsar Krypton 2 FXQ35
The Pulsar Krypton 2 FXQ35 is a 384×288, 17 µm thermal clip-on behind a 35 mm lens. On the Johnson yardstick that is an estimated 515 m detection and 129 m recognition range for a standing person; Pulsar quotes 1,350 m detection. Its 515 m estimated detection range is the shortest of the 10 clip-ons here.

Box claim vs. what the optics support
One pixel of this unit sees 0.486 mrad (17 µm ÷ 35 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.486) × 1000 = 515 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.
- Publishes its NETD (<25 mK) — 16 units here do not
- Removable battery pack — a spare in the pocket doubles the run time
- 11 h published run time, 3rd-longest of 64 here
- IPX7 sealed — survives immersion, not just rain
- Records video and streams to a phone over Wi-Fi
- 19 oz hanging in front of the day scope's objective
- 384-class core — 1.7× less field of view than a 640 behind the same lens
- Estimated recognition only 129 m — inside typical shooting distance
- NETD published only as a ceiling (<25 mK), not a measured figure
