Review on 🔌 VersativTECH 3-in-1 Circuit Breaker Finder Multitool: GFCI Circuit Tester, LED Flashlight, and Accuracy in Identifying Power Source for Outlets by Doug Nelson

Renovating an old house and an electrical box that wasn't marked where they went. I plugged the transmitting device into an outlet and then walked over to my switch box and waved my wand over the box a few times. Now I know which switch is going off. This made the job an easy task. I also bought a zip tie to be able to attach the transmitter unit to individual wires and trace them to the switch.
