Like previous FLIR ONEs, the third generation FLIR ONE equips users with the superpower of thermal sight. Even in complete darkness, users can visualize small temperature differences through the lens of the FLIR ONE. Whether you’re trying to determine why your room is so cold, why your wall is starting to bubble and turn awful new colors, or just trying to find where your dog is hiding in the backyard, the FLIR ONE will help you see the formerly unseen.
