I have a FLIR One Pro iphone thermal camera, and I’ve been scratching my head trying to find the “Lock Span” function in the app. You know, the one that makes the camera actually useful? Without it the display is a constantly changing disco light show and you can not use it to survey anything efficiently.

Turns out they simply removed the feature from the app, to encourage you to buy a new product, which still has the lock span feature enabled.

Needless to say, fuck that, I’ll be buying the CHINESE cheapass equivalent thermal camera next time.
