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

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.

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

Could not adjust to work on any breakers, junk

Ive used a handful of these style circuit breaker finders, and they never work 100%, but they always help to narrow it down to 1 or 2. That alone can save me a lot of time. This one is no exception. Its important to remember to slowly scan all the breakers at least once before diagnosing. It has a sensitivity adjustment. I started it out on max, and it showed most of the breakers as positive. I turned it down about half way, and it showed 2 breakers that were next to each other. The first one I tried was the correct breaker. I also like that it comes with a wiring checker and gfci tester. If you dont already have one of those, this becomes a very handy set. Overall a great tool. Highly recommended.

I have a lot of double single pole breakers, So the unit triggers even on the half of the breaker that is a different separate circuit. However the audible tome will be louder for the correct half; and the feed wires, if sufficiently separated, will signal very discretely on only the correct circuit. So it works just fine. In fact works great.

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.

Works like advertised and you get a nice case for storage

Dont waste your money it is crap does not work

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