Stopped trusting my multimeter after a 737 incident in Atlanta

Had a 737 come in with a weird static issue last month. Checked continuity with my usual fluke, everything looked good. Then the senior guy next to me pulled out his megohmmeter, found a hairline crack in a connector pin that my meter couldn't catch. That crack was arcing out, causing all the problems. It cost two days of downtime because I missed it. What meter do you guys trust for finding those tiny intermittent faults?

Ah man, don't beat yourself up too bad. I once spent an entire afternoon chasing a ghost fault in a control panel, finally found out my trusty old Fluke was just as clueless as me. Turns out the battery was low and giving false readings. Talk about a humbling moment. Sometimes you just gotta accept that a regular meter can't see the sneaky stuff, like that cracked pin you mentioned. I keep a little $30 cheapie around now just to double check my main one, because if both meters agree, it's probably real.

Straight up, megohmmeters are totally different beasts. Can't really compare apples to oranges there.
