Works through walls too
I just bought this to use in my older house and it has worked great for finding the breakers and even wires in the wall! I find for the walls it can be a little hard to trace as I feel like the wires have to be within 1-1.5" deep with the sensitivity maxed out and you can loose the signal being as little as 1/4" off from the trail, but it totally works and let me trace a few wonky paths so I could figure out exactly where the wire was moving in my walls and even to a buried junction box. I also really like the manual adjustment since it lets me hone in the breaker real quick and I don't have to scan the breaker like you see with the auto-adjusting ones. I just go to the breaker on about "half" sensitivity, move fast, and when I hear the beep I just drop it to lowest immediately and find it every time. Also due to the manual aspect of it, it let me figure out that a circuit was being served by 2 breakers and tracing which wire went where within the 14/3 wire sleeve itself since I could turn the sensitivity down so low. The socket tester works well too from the few tries. Only real issue I noticed is if you have any of the circuit based dimmers that basically everyone uses now since LED lights need them for dimming, it'll also send a signal in the line that this can pick up. It's real obvious though as it beeps much faster and sounds funny compared to how the device normally works, so either just ignore it and follow the normal beeps or turn off the light, surge protector, etc. Great device and wish I had one sooner to figure out all this weird wiring and no constant breaker switching either!
