Saved me a ton of time finding the right breaker—works through drywall and even block

I used the Klein Tools ET450 Advanced Circuit Tracer Kit on a troubleshooting job in Toronto where the panel wasn’t labeled properly (classic). Once the transmitter was connected to the circuit, the receiver sensitivity made it straightforward to isolate the signal and confirm the correct breaker without playing guess-and-check. What impressed me most is that it’s built for energized and non-energized breakers, fuses, and wires, and it’s designed to detect the signal through drywall, cement block, and even underground.
