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

Its a useful combination tool for testing outlets and identifying circuit breaker for that outlet.

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.

Got this to map out the electrical outlets for my new house when the electricians didnt bother to put the right info on the panel. This worked perfectly for every single outlet/circuit that I tried. This is really handy and Im really glad that I got it, even if I only need it for one use (if I labeled them all correctly). The only anomaly, there is an outlet that ZI feel is improperly installed, but when I plugged the receiver in to test the outlet, the two lights lit up green to say that the ground was fine. But when I plugged it in - the lights for the entire circuit shut down... Maybe the problem isnt with the ground, but I was sure that there was some problem that this should have detected. But I really love how simple and easy-to-use this is. It really is great. It even comes with a 9-volt battery, which I think is rare (in my experience).

It works like a charm

50+year old building. Built on 3 times. 3 rental units. 5 breaker panels. This tool was a life saver for me.

Tried this in my office. Very difficult to calibrate. I could never narrow it down to just one circuit breaker.

Got my Item very fast and in good condition. I would buy this again.

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.

Works as described

I wish I had one of these a long time ago. It works for me. As long as you understand you need to start out with the receiver on high sensitivity them gradually decrease it to lower sensitivity (go from general to specific to zero in one the exact breaker), you should be fine. The transmitter device seems to be exactly like one I already owned and are sold by themselves. It may just send some kind of signal the receiver detects. If you have an old home with multiple wiring revisions done over the years, this is a kit that will save you a lot of time.
