Never knew this tool existed, but glad to discover this and it works great! It is very sensitive, so you have to move slowly over the breakers and adjust the tool setting as necessary. Once you get a signal, decrease the sensitivity again and go over the breakers again. Eventually you should be able to isolate your circuit down to a single breaker. Unsure if a name brand tool is easier or faster, but at least this tool work for a fraction of the price.

I finally got a chance to use this and it worked out great you will need to adjust the sensitivity down or you will get false indications , I guess feedback tru the buss in the panel

The transmitter seems really powerful as the signal can bleed into adjacent lines/breaker, even with the lowest sensitivity on the receiver. Overall, it works ok. Was able to locate the correct breaker. The plug tester is an added bonus.

The wiring in my house is crazy. One room in my house is supplied by three different circuit breakers and the only way I would have ever figured that out is using this tool. With this tool, I was able to simply & quickly identify every receptacle that is controlled by each breaker. Just plug-in the transmitter, & take the sensor probe to your circuit breaker box & touch it to the front of each breaker to instantly find the correct one, the one that beeps. It is very sensitive, so it might beep on more than one breaker, but whichever one beeps the strongest is the one that’s correct. It seems to be made of high-quality and strong materials, and gives you instant readings to determine which circuit breaker is connected to a given wall outlet or light socket.

Used 1 time and it worked well. Per the instructions, turning the sensitivity low and then increasing it if it’s not indicating which circuit breaker is the target. Happy with it so far, have an older house and changing out some older, worn, yellowed plugs and switches. Home use.

Doesn't work. Beeped no where near the actual circuit. Wasted a good 15 minutes of my day. Do yourself a favor. Get a long extension cord, plug in a light or a radio, and run it out to where you can see or hear it and start flipping breakers.

I got it to track down some deenergized plugs. Sender is not powered so only works on powered circuits

I bought a cabin which had a bunch of bad GFCI's and a few wiring problems. I used this to test them and to find the correct circuit breaker to turn off when I replaced the bad GFCI's and while repairing wiring. I have two breaker boxes, with the finder it was easy to locate the correct one. Finding the correct breaker was a little harder, you have to adjust the sensitivity lower until just one breaker causes it to beep. On max sensitivity multiple breakers will beep. Once I turned off the breaker, I verified that the outlet tester showed the power was off- the green LED's were off. The outlet tester is easy to use, just plug it in and the LED's tell you if it's wired correctly.
