The fire department I'm on is raising money to buy a thermal imaging camera. We had the dealer come to the station with one once and we got to play around with it. Pretty cool. I'd buy one in a minute if I had the $14000 sitting around. Maybe then I could find that skunk that's hiding under the boathouse
It picks up heat really well and you can see in just about anything. Smoke, dark, snow, etc. The price is the only drawback.
