I keep hearing techs say they don't need to carry a multimeter anymore
I saw a real change in my own work about 3 years ago. I was getting by with just a voltage sniffer and a parts cannon approach. Then I had a string of 5 calls in a row for a weird fridge issue where the sniffer lied to me. Pulled out my old Fluke 117 and found a floating neutral on the board that was giving false readings. That week cost me about $400 in wasted parts and callbacks. Now I won't even open the truck without it. Are we really okay with ditching the most basic tool for guessing? What are you guys using to actually verify voltage under load?

My sniffer once lied to me too.

I mean, it's just a sniffer though, right? Like they mess up sometimes but it's not the end of the world. Maybe we're taking this a bit too seriously.

So a sniffer "messes up sometimes" and that's fine? How many callbacks and wasted parts does it take before it's a real problem? That floating neutral story is exactly why a real meter matters. What happens when the sniffer lies on something more expensive than a fridge board?
