The $89 thermal camera I bought on a whim paid for itself in one job
Picked up a cheap Seek Thermal for my phone last month after my Fluke meter couldn't find a failing PSU in a rack at a client site in Akron. Found the hot spot in about 4 minutes, swapped the part, and billed the hour. Has anyone else had luck with sub-$100 thermal gear, or am I just getting lucky before it dies?
