A+++++ EASY TOOL TO USE!! Just reduce the sensitivity RECOMMENDED

Nothing like searching for just the right circuit by turning them off one at a time. This works very well just be patient. I see negative reviews and I do not understand why.. Just reduce the sensitivity until you can pinpoint the circuit, that is all. My wife went to the power box and in about 30 seconds had the correct one, first try. Now I will say that is you are a pro then this is not the one for you, a heavy duty one is about $200. For $30 this is a perfect unit for occasional use by a home owner. If you are so impatient that you are not able to make it work, then call an electrician. RECOMMENDED

Already paid for itself

To me, this is worth a 5 star rating. This unit has already paid for itself plus some. I don't understand the "junk" reviews on this. I have always been afraid of messing with anything electrical, but the house I purchased has a breaker box with about 40 breakers in it. The previous owners didn't specifically mark each circuit breaker. I'm putting appliances in the basement and found out that the outlets behind and to the side of the refrigerator weren't working along with the fan and light in the stove hood. Other outlets around them worked. There weren't any breakers off in the box, so I used this tool to figure out which circuit breakers went to the surrounding, working outlets. I then flipped off then back on, each circuit breaker on either side of the newly marked breakers. Success! So now I not only know which breaker goes for what, I was able to determine that the breaker for the outlets that weren't working just needed to be reset since it didn't flip the breaker to the off position. Now I will also be able to install the new kitchen light I purchased instead of calling someone to come and do it. So this device has already saved me at least one electrician call.

Quick, easy, and effective.

It seems like folks post reviews when things don't work, so I figured I'd better add my review since this item worked great. Our 200A panel was new in the early '90s and there's plenty of wires in there. I plugged the transmitter in and walked downstairs to the panel and found the corresponding breaker right away. I couldn't be happier. Directions were good and it came with a decent GP 9V battery. I'll reuse the packaging to hang it on my pegboard in my workshop. Bottom line - so far so great. I'll update this if I run into any durability issues.

Works well and reliable

Very effective tool, I use it on almost every repair call. It made me look like a pro when I labeled all the sub panels for a commercial warehousing customer of mine who berths hundreds of food trucks boats and RV's. When they need to know where a breaker is in one of their 9 panels they can find it because they are all labeled now at the receptacles. It works for two and three leg circuits without neutral legs better than I thought it would. I used alligator clip jumper wires and pins to connect the plug to the various twist lock and range receptacles that the food trucks plug into for the night. It is a little hazardous to have open hot wires using alligator clips, but it works safely and well well with a little caution and a vigilant helper. I am very happy. I have also used it to locate GFI feeds and test GFCI receptacles. It is a good tool and a great price. It is not a hard core unit in the long run, but it is not crummy cheap either. I am a professional repair contractor and although I am not destructively hard, am very hard on my gear in normal use, electrical work is a rough discipline. I drop things a lot, and I use it up, burn it out, and play it as productive as possible. I have no problem with the fact that a saws-all lasts me about a year during rough in work. The tool makes its money several times over. The plug-in on the breaker locator broke when I was testing a GFCI. The ground prong came out of the plastic body. The prongs are good thick stainless steel but it needs a larger chamfer ring to hold it into the plastic, at least the ground prong anyways. I absent minded threw both the plug and receiver away immediately on the job site with some other debris and wire clippings. I looked closely at the body of the plug and hastily decided not to try to open it and fix it. I figured I would just buy another one. Now I wish I had saved it and looked closer later. I have a entry level quality toner kit also and love it. I have dropped it twice and opened it and fixed the antenna cartridge and the speaker twice. I can not see the point in spending over 100 bucks on instruments that are gonna get beat up, or stolen anyways. This is an excellent tool whether you are a home-owner or a professional. The seller gets it out quick and with good packaging. If I am more careful with the plug I am sure it will not break again.

The perfect tool to map your circuit breaker -- definitely recommend.

Make sure to read the instructions. Once I got the hang of this, mapping my new circuit breaker was cake. In a nutshell though, you: (1) plug the thing into an outlet (2) go to the circuit breaker and set the sensor to the highest sensitivity (3) hoover it very closely (or touching) the circuits -- going up-and-down or side-to-side (depending on the circuit layout) (4) once the sensor detects the right circuit -- in the general vicinity -- continue to reduce the sensitivity until the alarm ONLY goes off when it's directly over the right circuit. I know the above sounds involved -- but once you do it a couple times -- the remaining ones only take 10-15 seconds.

Awesome gadget. Works perfectly. Wish I had this 20 years ago.

This gadget allowed me to completely and accurately map my circuit breaker panel. The original "notes" written inside my panel door were poorly done by the electrical contractor on our new home. Basically gibberish, incomplete and quite worthless. What happened to careful craftsmanship? Well, enough of that. This device works as advertised. The key,as mentioned in many other reviews, is to fine tune the sensitivity thumbwheel until the beeping and signal light indicate on ONLY ONE BREAKER. Then you know you've found "the one".

Excellent - and the manual sensitivity adjustment is the way to go.

Worked perfectly. There were others that calibrated automatically but the procedure looked tedious. And my experience with stud finders that calibrate automatically has made me long for the older stud finders that had a sensitivity knob like this item does. I turn up the sensitivity and vaguely track down an area. Reducing the sensitivity as I narrow it down. Finally when I have a candidate I turn the sensitivity until it just cuts off and then check everywhere to see if it turns back on. Then just barely increase the sensitivity until it's on and flip the breaker and it should stop. Pretty much just like the instructions. So far it has worked every time. Nothing on my breaker panel was labeled. It all is now. Plus I plan to put small stickers on each outlet with the breaker number. I'm a label maker mad man. Update: Just traced the circuits on another house. It worked perfectly 90% of the time. The other 10% I could narrow down to just 2 or 3 breakers. So I didn't have to keep turning all the breakers on and off. I am very pleased with this. Especially manually adjustment. Long live manual adjusting and to heck with all this self driving cars nonsense.

Manual sensitivity adjustment puts me in control. Which is best (IMO)

Having the adjustment knob for sensitivity gives me the peace of mind when I'm using this CB finder. I've been able to map out my entire house regarding which outlets are on which CB. It's all about technique with this...I plug the transmitter into an outlet, head down to my panel, then with the sensitivity to it's highest setting touch the breakers and (as per instructions) slide the receiver up and down the breakers. It typically starts beeping the second i put it on the panel..so i dial it down just a touch, then keep dialing it down until only the strongest of signals is being picked up...typically 2 or 3 breakers. Then i just dial it down a bit more until only maybe 2 are beeping...then 1...and boom i found it. If you want to be 100% certain you found the correct breaker, just shut off the indicated breaker and the signal from transmitter should cut out completely, even if you put the the sensitivity know all the way up. Once you get the knack of this, you'll be able to label your breaker panel box in no time! I would highly recommend this unit over a unit that has automatic sensitivity adjustment because it gives you the control and therefore the confidence to know a reading is accurate. You could also use it for lighting sockets or exposed wiring by utilizing alligator clips, etc.

Great Product

This product is great for locating breakers or testing outlets. I used the Outlet tester on a few outlets and light fixture wiring and it worked well. (I tested the light fixture wiring with my screw-in light bulb base, which has outlets on it.) The key to using the circuit breaker locator properly is by operating the manual Sensitivity Adjuster. I read the manual, but practiced using it on outlets and their matching breakers, which I already had labeled. Once I felt that I got the hang of it, after a few minutes, then I used it to locate the breaker for my outlet in question. I started on my main panel, the device beeped at the breaker for my sub-panel, I headed to my sub-panel, and the device finally beeped at the exact breaker on my sub-panel. (I had to readjust the sensitivity at the sub-panel, but that only took a few seconds.) If you're looking for a "smart" device, or something that does all the work for you, then this device is not for you. If you don't mind a bit of manual work to get things done, then this device will work for you.
