Finally caved and bought a thermal camera for $200 after a customer swore by it
I thought it was just a gimmick for fancy inspectors, but I found a fridge leak in 5 minutes that would've taken me all afternoon with soap bubbles. Has anyone else had one of these things pay for itself fast?
That's the thing with these tools, they seem like overkill until you actually need them. A buddy of mine used his to find a hot breaker in his panel that was barely warm to the touch but was actually failing inside. Caught it before it turned into a real fire hazard. Another time he tracked down a draft around a window that the weatherstripping was supposed to seal but had a tiny gap you could never see with your eyes. So yeah, $200 sounds like a lot upfront, but when it saves you from ripping out drywall or replacing a whole appliance, that's money well spent in my book.
