I thought one would be easy to find.....guess not. I apparently have a 'non contact' detector, which picks up any current from 4" away, making it useless in trying to find the hot wire in a box.

I want one that will read through the insulation, but has to be almost touching it to sense. Basically so I can easily distinguish the incoming hot from the outgoing hot in a junction box. Is there such a thing?

Google: "adjustable non-contact voltage tester"

I have 5-6 of them. They have a little wheel on the side to adjust the sensitivity. Work great.

Bingo.....sounds like what I need, getting hundreds of 'non contact' detectors online, but haven't been checking details for a 'sensitivity adjustment', but now I see some. Thanks.

While they work great most of the time they also provide false positives when Romex is close to other current carrying Romex. When in doubt always use a meter.

I use a Milwaukee non-contact sensor and it seems to be less sensitive to phantom voltage. Even has an LED light in the end, surprisingly helpful. Got it on Amazon.
