- Thermal-optics buyers comparing real-world range
- Worth noticing
- The catalog reports manufacturer claims averaging 2.3 times its detection estimates across 60 units with published claims.
Field notes
Thermal Ranker derives three range estimates from published pixel-pitch and focal-length figures, using 2, 8, and 13 pixels across a 0.5 m human dimension as its detect, recognize, and identify thresholds. The catalog also records refresh rate, weight, battery, video, ballistic-calculator, and price information where supplied. Its own caveat matters: the figures model the optics rather than measuring performance in field conditions.
