Quickly locate the right 120v circuit breaker or fuse, without guessing!
Plug the UL-listed transmitter into an outlet on the circuit you want to locate. (Also works with your own screw-in plug adapter for light fixtures.) Go downstairs and run the receiver's tip over the breakers or fuse rows until the arrow illuminates and the speaker beeps. That's the breaker or fuse you want. Won't trigger ground fault interrupters.
Manual/automatic off. 9v battery not included for receiver. Patented.
