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

GFI shows open ground always, very poor breaker identifier. Waste of my money. I bought the Kline tester, works perfectly. Stay away from this unit.

Dont waste your money it is crap does not work

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.

Remodeling the house and replacing sockets to current codes, this is an old house. Circuit breaker finder helped me find the right lines to turn off. Easy to use and in my low budget raange.

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).

Two functions in one product: Circuit breaker finder and GFCI tester. Fairly easy to use, but it does require some adjustments on the sensitivity using the adjusting knob on the scanner. Nine-volt battery is included, but not connected. Be careful when opening the battery cover as its tough to remove and will go flying if you are not tightly holding the cover and the rest of the scanner. Use gloves with a rubber grip for easier opening. A nice case with a zipper closure, but it could be improved with a label so one knows whats inside it. Since the case it black, its difficult to use a marker on it and the bumpy texture makes it hard for any white marker or adhesive-backed label to stick. Works well for plug-in / outlet circuits, but not for wall switches or screw-in outlets. Adapters for these sorts of outlets would be an excellent addition. Directions are well written but printed on very thin, flimsy, onion-skin paper. The paper is very easy to tear, and will be useless the first time it gets wet. I suggest taking an image of the directions, scanning them or both. Also, it would be nice if the vendor added a QR code on the scanner for use and care directions -- and used better quality paper. There is some sort of bar code on the scanner, but its not a QR code. Made in China. Reasonably well priced at about $28 at the time of our review.

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.

Needed to identify breakers that controlled outlets. Adjusting the sensitivity made the accuracy perfect. Very easy to use.

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
