I have used Flir, Pulsar, and Bering Optics for scanners over the last 3 years. The best image while still having a good FOV and good PID has been the Bering Optics Phenom. I just tested one a few months back, and it was so good I sold my Pulsar Helion XP50 immediately in preparation to buy one. Now, Bering is telling me they are releasing a Phenom 640x480 12μm with an even better image. Night Goggles is planning to start carrying this 12μm model in about 3 weeks. The following video was captured with the 17μm 640 x 480 Phenom and it still is very good. The Phenom has a ton of compression on the video so the view through the eyepiece is way better. The Phenom has a 4 year warranty. You will be amazed at the image quality of this thermal.
