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

When used it show a few breakers so I found my self cycling breakers that were near it till I found the right one. However once you open the right breaker the device wont sound so it does work.

I own lots of these, and I am always ringing out wires... if you read bad reviews, well, that will happen with these products... mainly because, they are very unique, tempermental, and each brand has its own personality. for the newb, it can seem like, its too hard to trace, but with some trial n errror, u learn what works. how? test on a circuit you know both ends... be sure to pick one in the middle of the breaker panel find a way to test, so it works, adj. sensitivity, distance, speed, etc. once you perfect one that works, u can then move on to the mystery circuits... overall, for the receptacle gfi tester, and the tracer, this is an amazing value, and it works! recommended! 4.5 stars

My house was built in the 1950s and added on to many times by people that didnt always know what they were doing. As a result, my wiring is a hodgepodge mess with outlets on different sides of the house sharing the same circuit in some cases. This unit worked on a few of my circuits, but most were not accurate at all (would signal on the wrong circuits). I have a mix of double and single pole breakers, all covered by a sheet metal panel. Playing with the sensitivity seemed to help, but it varied so much from circuit to circuit that I found it was faster to just start flipping breakers on and off while talking to my wife on a hand held radio rather than fiddling with the sensitivity setting each time. The unit seems well made, and is very easy to use. It would probably work much more effectively on a newer house with newer (and cleaner) wiring. But for my situation, it didnt work at all unfortunately.

El producto es muy complicado y no es certero al usar e encontrar el breaker

We had changed out our load center some years back and never got around to labeling the breakers, well thats not good. When you need to know, you often need to know at that exact moment, what breaker is what, so I took this thing and was able to quickly go from room to room or outlet to outlet and find the source breaker/circuit, now no more headaches when I need to find a particular one. This also makes a great NCV detector, so once its duties are done as a finder in the home it can still be helpful later on.

Works pretty good considering the price. New it wasnt top of the line going in.

It just trash

Be sure to read the instruction manual. Purchased this to trace a circuit....and it worked flawlessly. Highly recommend.

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.

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