Pin testers are overrated, here's why I stopped using one on the bench

I spent the last 8 months at a regional shop near Dallas chasing intermittent faults on Collins radios, and I finally ditched my pin tester for a good old fashioned wiggle test with a DMM on the harness. The pin tester kept giving me false confidence on a cracked solder joint that only showed up under vibration, which burned 3 days of troubleshooting on a 737 something. Anyone else find that leaning on those fancy testers just masks the real problem until you physically move the wires around?

Different tools catch different faults, and the wiggle test misses plenty too.
