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

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.

I own lots of these, and I am always ringing out wires... if you read bad reviews, well, that will happen with these products... mainly because, they are very unique, tempermental, and each brand has its own personality. for the newb, it can seem like, its too hard to trace, but with some trial n errror, u learn what works. how? test on a circuit you know both ends... be sure to pick one in the middle of the breaker panel find a way to test, so it works, adj. sensitivity, distance, speed, etc. once you perfect one that works, u can then move on to the mystery circuits... overall, for the receptacle gfi tester, and the tracer, this is an amazing value, and it works! recommended! 4.5 stars

Good

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.

We have a home built in 1959. The breaker box has a few labels, but they mostly identify the 220 circuits for the stove top, oven, dryer and water heater. As for the rest of the circuits for lights and outlets, few of them are marked and Ive found a couple of them marked wrong. This works best with two people so you dont have to keep running back and forth. The sending unit is plugged into an outlet and the receiving unit is passed over the circuit breakers. When you have the active circuit, the receiving unit lets you know. Once you have gone through your whole house, there is never again that need to flip circuits on and off trying to find the right ones.

Be sure to read the instruction manual. Purchased this to trace a circuit....and it worked flawlessly. Highly recommend.

The purpose for getting this device was so that I won’t have to flip all my circuit breaker switches off to find the right one. This did not work for me. I read the instructions, watched YouTube, read Amazon reviews for tips, adjusted sensitivity, the position and the distance of the toner - all of which did not help. It identified multiple, and the ones identified were not the right circuits! At one point, the toner made noise in two completely separate electrical panels while probing! (Mind blown!) I plugged in the transmitter to different receptacles, and in different rooms. Lastly, I took it to a friends house for him to try. He knows a lot about electricity and he did not spend as much time as I did with it before he determined that the device doesn’t work. We have conclude that this thing doesn’t work on U.S. homes built on or after year 2004. I was very hopeful and excited when I ordered the device - ended up disappointed.

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

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.
