Finally bit the bullet on a thermal imaging camera for the shop
Spent about $800 on a Flir One Pro last year, thinking it would be a neat toy for finding electrical faults. Turns out it's saved my bacon more times than I can count. Just last week, had a 6.7 Powerstroke with a weird intermittent miss. Scanner showed nothing, but the camera picked up one injector connector running 30 degrees hotter than the rest at idle. Found a corroded pin causing resistance. Without that heat signature, I'd have been chasing ghosts for hours. It's not cheap, but for diagnosing electrical issues, coolant flow problems, or even a dragging brake caliper, it cuts diagnostic time in half. Anyone else using thermal imaging regularly, or do you still think it's just a gimmick?
