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

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

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

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.

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).

I often thought something like this would be a godsend to a homeowner who does minor electrical repairs. Instead of turning on and off every breaker in the house, requiring multiple clock resets, you plug this into an outlet, go down stairs and Voila, you find the right breaker and turn it off. Of course you do the necessary verifications afterward, but this saves you a lot of running around (especially if you are alone). When I used this for the first few times, I was convinced it did not work. So I held off doing my review, convinced it was user error and having used this on multiple breakers since, figured out that was the case. If you have the sensitivity on low (spinning wheel adjustment you turn it on with), you will get no breakers showing as the right one. If you turn it on high, you will get multiple breakers. The secret is to turn this thing up or down till you get one. When you initially turn it on, it is on max by default, rotating down, it gets lower. I found this super confusing. The reverse would make more sense, or if the light got duller when low and brighter when high. I kept turning it the wrong way. But that is me. However I checked 6 outlets in my house and initially some showed multiple breakers until I adjusted the sensitivity down. Most often adjoining, but one was not. Even testing on one of those outlet extenders (ones that go over an outlet and add outlets, USBs and even a shelf), it got the breaker. For the most part, I have some breakers labeled, but like most houses; additions and changes to the structure make finding the proper breaker a bit of a hunt and peck operation. Not all are labeled. The part you plug in also functions separately to check for the status of the outlet. I know years ago at my Mom’s there was this one outlet that used to give me a shock each time I used it and I found out using one of these types of detectors that it was not properly wired. An electrician fixed that one. He was surprised that it was even noticed. Mine you, I got a shock every time I used it, so hard not to notice. Tools like this can help you make your house safer. One thing I nearly failed to mention is the nice carrying case this comes in. So often tools go in a bag or drawer and sit until you need them. This case holds everything including the instructions and to me is a great addition to keep the integrity of this set of tools.

This testing and tracing system works well and can allow one person to identify every outlet connected to a load center without help. I would only add a means to attach the tester/sender to non 3-prong outlets, such as light sockets or via alligator clips. It does all that it claims and does it well.

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

This is a great tool to track down circuits in your home or office. easy to use, and works well. does a good job of helping you figure out what is what in the breaker box.

This tool will not accurately detect a breaker at any sensitivity

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.
