Showerthought: manual VOM vs my old Fluke meter on a 737 pitot heat short

Spent 3 hours chasing intermittent pitot heat faults on a 737 with my fancy autoranging meter because it kept jumping around, then borrowed a crusty Simpson 260 from a retired guy in Tulsa and pinned the chafed wire in 20 seconds flat, so now I'm wondering if anyone else keeps an analog meter in their box just for noisy shorts like that.

Wait, a crusty Simpson 260 from a retired guy in Tulsa? That is some serious old school magic right there. I still can't get over how those old needle meters can just cut through the noise on a chafed wire when a modern autoranging unit is bouncing all over the place. The needle gives you an actual average reading instead of a screen full of numbers freaking out every half second.
