Dropped $400 on a proper thermal camera for my shop and I'm split on if it was worth it.
I got tired of guessing with a temp gun on weird overheating laptops. The camera showed a failing voltage regulator on a board that felt evenly hot to the touch, which was cool. But that's maybe one clear win in three months, and most days it just confirms what I already knew. For the other techs out there, do you find a thermal imager is a must-have tool or a niche gadget that mostly collects dust?

Honestly, it's one of those tools that sits in the drawer for weeks, then saves you an hour of head-scratching on a single weird job. I bought mine for finding bad connections in panels (which it's great for), but the real surprise was spotting a shorted ceramic capacitor on a board that looked perfect. The temp gun just showed a warm blob, but the camera pinpointed it. For me, that one find a year makes it worth having around, even if it feels like a luxury most days. It turns a guessing game into a sure thing, which is sometimes all you need.

Totally get what you mean about the luxury tool feeling. Mine collects dust until something truly weird pops up, and then it's a lifesaver. That moment when you go from guessing to knowing exactly where the heat is coming from changes everything. It feels less like spending money and more like buying back your own time and sanity on a bad day. Having that one sure thing in your toolbox makes the tough jobs way less stressful.

My old Fluke thermal camera found a failing terminal block on a motor starter that was just slightly warmer than the others. Like @taylorknight said, that shift from hunting to knowing is huge for your peace of mind. It sat unused for months before that, but spotting that one hot spot before it caused a shutdown justified the whole purchase. The visual proof lets you fix the real problem fast, not just swap parts hoping. For those occasional mystery faults, it really does pay for itself in saved frustration.
