This is to be filed under "Justifications for buying something cool". A really bulging file.... The current thread regarding a lost Model X key fob has brought forth the demonstration of a FLIR device being useful for finding it: Fob missing somewhere inside Model X - any guesses? That's pretty compelling...but $220-250 as insurance against something not hugely likely to occur isn't quite enough to push me over the edge. Have any of you other stories for which a FLIR has been truly helpful - rather than merely gadgety? I'm seeing a FLIR One - it links to an iPhone - being offered on Amazon right now for $221: Amazon.com: FLIR ONE Thermal Imager for iOS: Camera & Photo. Stand-alone FLIR devices go for $1,200-$3,500 and I'm sure a lot higher. *And for those of you who knew as little as I did, "FLIR" stands for Forward-Looking InfraRed.
