Pro tip: my $150 thermal camera found a hidden leak in a finished wall

I was doing a retrofit in an old house and the client kept getting false alarms from a moisture sensor. I mean, the wall was dry to the touch. I bought a basic thermal camera for about $150 to try and find the problem. It showed a cold spot behind the drywall, and sure enough, there was a tiny pipe leak. Has anyone else used one of these for troubleshooting? I'm thinking it might be worth keeping in the truck.

Worth keeping in the truck" is right. I saw a contractor on a home show use one to find bad insulation in an attic. It seems like one of those tools that pays for itself the first time you avoid a bigger problem.

Just creates more problems than it solves.

Found a hidden leak in my bathroom wall with one last month.
