Dont waste your money it is crap does not work

You simply plug the tone generator unit (which also works as an outlet tester) into an outlet, and tone is automatically sent to the circuit box. If the circuit is off, however, the tone sender unit is not powered, and no tone is generated.

I have several UNI-T instruments and I have found them to be well made and less expensive than bigger name brands. The circuit tester function of the device works well and is clear to read and understand thanks to the onboard labeling showing what the light combinations mean. The GFCI tester worked perfectly. The circuit breaker locator function takes a little more effort to learn to use effectively, but I quickly found a way to make it consistently locate the correct breaker. When I started using the locator probe I found that it would trigger prematurely if I touched the white part to the circuit breakers. Typically more than one circuit breaker would trigger the locator tone as I got close to the correct breaker and I couldnt adjust the sensitivity to prevent that (either there would be no detection or multiple detections). Remembering something I discovered with my underground wire tracer, I lifted the probe off the circuit breaker by about 1/4 to 1/2 and then scanned for the correct breaker. This resulted in perfectly reliable operation. That may be something specific to my brand of circuit breakers or the length of the wire runs in my home, but if you struggle with getting an accurate reading, give it a try and see if this is a helpful tip for you too.

Worked just like advertised even came with a case and battery.

We have a home built in 1959. The breaker box has a few labels, but they mostly identify the 220 circuits for the stove top, oven, dryer and water heater. As for the rest of the circuits for lights and outlets, few of them are marked and Ive found a couple of them marked wrong. This works best with two people so you dont have to keep running back and forth. The sending unit is plugged into an outlet and the receiving unit is passed over the circuit breakers. When you have the active circuit, the receiving unit lets you know. Once you have gone through your whole house, there is never again that need to flip circuits on and off trying to find the right ones.

This device gave incorrect readings from the outlet to the breaker box.

The accuracy was a little questionable. It was lighting up on more than 1 breaker so it was difficult to tell which breaker it was. My dad brought his Klein and it worked flawlessly. This tool is fine if you are good with approximate. Ill be returning unfortunately.

The purpose for getting this device was so that I won’t have to flip all my circuit breaker switches off to find the right one. This did not work for me. I read the instructions, watched YouTube, read Amazon reviews for tips, adjusted sensitivity, the position and the distance of the toner - all of which did not help. It identified multiple, and the ones identified were not the right circuits! At one point, the toner made noise in two completely separate electrical panels while probing! (Mind blown!) I plugged in the transmitter to different receptacles, and in different rooms. Lastly, I took it to a friends house for him to try. He knows a lot about electricity and he did not spend as much time as I did with it before he determined that the device doesn’t work. We have conclude that this thing doesn’t work on U.S. homes built on or after year 2004. I was very hopeful and excited when I ordered the device - ended up disappointed.
