Tried a thermal camera on a fridge call, now I'm hooked

Had a no-cool call in a commercial kitchen in Newark last Tuesday, compressor was running but temps were all over. I borrowed a FLIR One from a buddy just to check evap coils, and it showed a clear 15 degree split across two circuits that my gauges were totally missing. Turns out the TXV was stuck on one side, something I'd have chased for hours with the old touch-and-guess method. Has anyone else used a thermal imager to catch partial blockages that don't show up on pressures?

Man, my hand just got a promotion to obsolete after watching that video.
