Hot take: I started using a cheap voltage tester for panel diagnostics and it saved me a ton of time.
Everyone at my shop swears you need the expensive multi-meter for everything, but I got stuck on a weird power issue at a commercial site. The main panel was showing inconsistent voltage on the keypad line. Instead of pulling out the big tool, I grabbed a basic $15 non-contact voltage tester from my bag. I ran it along the wire run and found the exact spot where the induced voltage was dropping, about 20 feet from the panel. It was a pinched wire in a conduit bend. Fixed it in 10 minutes. Has anyone else found a simple tool that works better than the 'right' one for a specific job?

Man, I was a total multi-meter snob until something like this happened.
