The Adder V2 LRF 35-640 runs a 640×512 core at 12 µm behind a 35 mm lens; the Varmint V2 LRF 35-640 runs 640×512 at 12 µm behind 35 mm. On the Johnson yardstick they detect a person at 729 m and 729 m and recognize one at 182 m and 182 m; the boxes say 1,800 m and 1,800 m. The Varmint V2 LRF 35-640 is lighter by 11.0 oz. Approximate prices are ~$3,795 and ~$2,995.

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.
