FLIR finally releases the new and improved FLIR One for $250!! The new FLIR One has an automatic calibration shutter and now works with ios and android! This is a much better form factor over the original FLIR One but in my opinion is still limited by the inherent low 80X60 resolution of the Lepton camera. The Seek uses a Raytheon EXC001 Microbolometer with 206X156 resolution which is 6 times the resolution of the Lepton!! As far as specs go the Seek is better on paper than the FLIR One but the FLIR One's app software is very stable and user friendly.
