UNI-T AC Circuit Breaker Finder with Integrated GFCI Outlet Tester AC 90-120V USA Plug + Adjustable Sensitivity Beeper Indicattion+ Flashing LED Light

So this circuit breaker finder is not bad at all. I tried it a few times in different locations and for the most part it worked for me. Only one instance it didnt work as expected. Very easy to use, nice and compact and comes with a nice carrying case. Overall not a bad product at all.

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.

UNI-T AC Circuit Breaker Finder with Integrated GFCI Outlet Tester AC 90-120V USA Plug + Adjustable Sensitivity Beeper Indicattion+ Flashing LED Light this is a sweet little gadget! Wish I had one of these when I was still doing remodeling work. Back in the old days youd have to plug in a light, 5hem hollar over to your buddy wife for kid, generally from the basement, hey! did it go out yet? Nope. Not yet... None of that nonsense with this little guy. Basically no problems getting it to work You start at the highest sensitivity and it did beep on about 4 circuit breakers then you dial down the sensitivity and then it didnt beep at all then you dial it up a just a little bit and then it beeps on just one breaker. brilliant. Just brilliant. One thing I did notice though is I have a power strip plugged into a power strip plugged into another power strip and I put the transmitter into that last power strip and that did not show up at the panel. So it does seem To be better if you plug the transmitter directly to a wall outlet. Would absolutely recommend this.

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.

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.

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

This tool will not accurately detect a breaker at any sensitivity

Works like advertised and you get a nice case for storage

Its only natural for the signal injected at the outlet to bleed over to other circuits. The receiver has to be able to filter the lesser signals and only beep on the strongest. This one does not. It signals on too many breakers to isolate the one I want. So, I took it out to my shed with 6 outlets and 3 breakers in the whole box. It signaled strongly on all 3 breakers. I moved it around and it still signaled on all 3. I spent quite a bit of time adjusting sensitivity to no avail. Im returning it and will hit the Home Depot a little later for a Klein. Oh, and the circuit tester shows open neutral on all breakers.

Works like a charm! Just gotta play with the sensitivity... start low.
