Question: Do I have to remove panel cover or can I simply scan down switches?
Document: I got this product about a week or two ago and just used it on the job. Ran the receiver over 3 different breaker panels and it beeped on one of the panels. scanned it twice over the same panel ignoring the first beep and trying to identify which breaker the second beep was pointing to. Problem is I had to actually remove the cover off the breaker panel and have the wires exposed for the second beep to go off. Even after that it would beep on the wrong breaker.
The good rubber skin, Orange easy to see. It works as stated. needs improvement;  the range is extremely short. must open panel cover to get reading. the on button is too sensitive to light taps. no attachment of trans to meter, easy to lose. needs warning sign on trans telling people do not remove, return to maint if found, etc. overall; the ranging gets tricky but you get the hang of it as it's automatic.
If you ever find yourself looking for a breaker by yourself. Then this is the unit for you. I hate shutting off every breaker to find the correct one. Plug this little jewel in and then go to the panel and scan the breakers, tones out when you reach the correct one...yes another great unit for homeowner or professional.
Read other reviews and was concerned it wouldn't work - tried it a few times with mixed results and thought I might even return it but then I decided to try it without the breaker panel cover on - bingo - works every time like a charm - extremely accurate - very valuable tool!
To those who advise to read instructions careful, what could be difficult to turn it on by briefly touching on/off button and scan panel twice? If you are lucky and it works in your house, does not mean it works everywhere. I have standard north american two storey house. It's reliably identifies single breaker, but 80% of the cases it's wrong. That leads to frustration. I tried on at least 10 outlets in my house.
I purchased Klein Tools ET300 from local HomeDepot,it works perfectly if you follow the instruction:scan-twice,second time it always give you a confirmed reading, then you push the power buttom again to reset for next reading. It's a wonderful tool to have.
I was hesitant to purchase this based on some of the bad feedback, but I'm glad I did buy it. It's very important to read the directions and do a scan of all circuit breakers so the tool can &#34;learn&#34; the breaker box. If you just randomly jump around, it will give you false readings. I have used this so far a couple dozen times and it hasn't disappointed.
In my opinion, the tool should come, or have an option to purchase, a case that would store the tool and the option kit, and also prevent the tool from being accidentally powered on. I'll either have to figure a way to protect the switch, or just remove the batteries when I am done using it, although that is a pain; you have to take off the rubber case and unscrew the battery compartment.
This does exactly what it sez it will do. Simply follow the instructions to set up the unit and then it will sense the circuit breaker that you are looking for.
Purchased this circuit finder along with the accessory kit. When the unit is used as per instructions it is bang on.It states in the instructions to do a scan of all circuits when trying to locate a specific circuit. This prior scan will give some false positives but then will zero in on the specific circuit during the follow-up scan.
Answer: yes
