StandardDeviation -

Having used all of the FLIR ONE models, I can tell you the new (Gen 3) FLIR ONE Pro is the best so far, by a significant margin.

cr0100 -

I tried the FLIR ONE Gen 3 PRO! The image quality is fantastic! The software needs work, though. It's great on an iPad (2017), but on my iPhone8 it's buggy as hell.Spot metering doesn't work, saved images are always a mix of visible/IR (no matter what the "mix" is that is selected in the application), and the palette selected always gets thrown to B&W when you take the first image - you have to select a different palette, then the one you want again and it works fine after that.Both iPad and iPhone running iOS 11.2.That being said: works wonderfully on the iPad - no issues there!
