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

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.

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

This breaker finder is So easy to use our use it on so many things even on different floors and it detected with no problem

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

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

You simply plug the tone generator unit (which also works as an outlet tester) into an outlet, and tone is automatically sent to the circuit box. If the circuit is off, however, the tone sender unit is not powered, and no tone is generated.

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.

This works well on standard breakers. It works okay on double circuit breakers, as it can be tough to determine which portion of the double breaker is actually the right one since the sensor head is large enough to cover both. The key in general is to adjust the sensitivity high enough to see the flow of electricity, but as low as possible, so that you can isolate the one circuit breaker that is actually active. The fact that the transmitter unit also functions as a circuit tester, and a GFCI tester, is a nice added feature. One 9v battery is required and is included. It is inside the receiver and must have the plastic wrapper removed and then be connected. The included zippered storage case is nice. The English translation of the one page Operations Manual is usable.

Works well. Better price than available in local retail stores. Now may breakers in the breaker panel is properly labeled.

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