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

while nowhere near as good as the more expensive pro-level ones, this one works well enough to map out the mystery fuse box in the basement. Mine had just a couple labels- and even those were wrong. Now I can swap outlets and lights without having to take out the power on the whole house. The build quality is light and it wont take abuse like a pro tool- but its amazingly inexpensive and works.

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

This tool will not accurately detect a breaker at any sensitivity

I had this, and less than 1 year it failed to take proper reading of the outlet wiring. So the gfci part of that unit will prematurely fail but can still use it for circuit breaker sniffer. One of the LED bulbs will fail prematurely. So if you have a good outlet that you know and you plug this gfci plug in and only one light goes on, its a sure sign of this failure. So now, I just use it for circuit breaker sniffer, and a separate GFCI tester. Not happy.

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.

Es perfecto para localizar los breaker en el panel haciendo facil todo el proceso y descartar pocibles errores acelerando la solucion.

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.

We just moved into a new home, but discovered the electrical panel was poorly labeled. This tool helped us map all the wall sockets to their appropriate breakers, so we can power down only the outlet we need without affecting others. This is an extremely useful tool to have around.

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.

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.
