Customer Questions & Answers

Does it include the wire splicer and snake in the picture?

Does the package come with the cable splicer and a snake? I'm just wondering because its shown in the picture.
Asked by: ReymondT
It is the transmitter and receiver only.

I have a GFCI which is wired wrong (hot and neutral are switched), need to find its circuit breaker. Can I use the Klein transmitter on this outlet ?

Asked by: Otto
As far as I can tell, as long as the outlet is providing power (even if the wires are wrong), the transmitter will transmit and the receiver will be able to receive/detect.

Can I clip one end of this tester to a circuit breaker and find the end of the wire through Sheetrock in another room?

Asked by: Rob
No this works on powered circuits only. You might try a tone generator. With that you add the power to the wire you want to find and then trace the area you want to locate the end of that circuit.

Let me start by saying this unit works great if you use it correctly and follow the directions. It would at best identify two breakers side by side as the target but I'm fine with that...it's better than having to test all 50 breakers to find the one you need! I agree with the reviews about the on-off switch being much too sensitive, but there is an easy fix! Take a small o-ring and insert it under the lip of the switch, this secures it from being turned on in the tool bag but still allows regular operation (see photo attached) This idea cures the problem and makes this unit worth the money.

Rated 1 out of 5 by from Waste of money As other have stated both the function and design are flawed. The power button is poorly designed, it was constantly turning on in my tool bag. Functionally, it consistently failed to identify the correct breaker, would give no reading at all or alert to multiple breakers. When following the instructions you have to set the unit up to "learn the panel" but if you are trying to label a panel by yourself the unit will time out and turn off in the amount of time it takes you to move the transmitter and get back to the panel, meaning you have to re "learn" the panel each time. I returned mine and went back to the old fashion way of labeling panels, turn everything in the house on, turn off a breaker and go find what is off.

Easy to use (follow the instructions... especially about letting the tool learn the panel.) Nice loud tone and bright green arrow... Signal was strong enough for the 1800 Sq Ft House I was working on. The price is right. The reason I'm giving it 4 stars instead of 5 stars is the annoying on-switch function. The switch to turn it on is very touchy. You barely bump it on anything the unit powers up. (In your tool bag)... A hard case would be nice or an On-Switch that has more resistance or one that you must hold down for a full one or two seconds. It functions this way during the off-cycle to power down.. You must hold it down to have it turn off, but you can turn it on by barely touching the switch...

The irritating thing is the stupid design of the on/off button. On the left of receiver is the on/off button, and any time it touches ANYTHING it turns on, and it will, so you can't put this thing in your bag, pocket, or truck, 'cause it will go off like your dog on a postman. All they need to do is have a positive on/off slide button; problem solved.

Though it does work as intended, the on off button is too sensitive. While in my tool caddy it will power on, would be better with a toggle. I will be returning this item.

I love this thing and so does my previous circuit breaker finder (my wife). Make sure you "train" it each time you search for a breaker. You turn off, if it was already on. Turn it on a few feet from the panel and then drag it down the rows of breakers, touching the plastic parts of the breakers. It may beep on the first one so ignore it. Keep it the same distance as you scan up and down the breaker rows. Once it beeps on a certain breaker, then shut that breaker off - the beeping should stop. Double breakers (2 switches in one breaker module) are a bit much for this thing. It will beep on the entire double breaker but not the one you need to shut off. You have a 50-50 chance of turning off the wrong one, but that is a small price to pay for not having to shut *all* of the breakers in the panel off, one at a time. Buy the alligator clips and screw-in socket plug option if you are working on lights and light switches. If there is no neutral wire in the light switch box, then you can cheat and connect the gator clips for the transmitter module to hot and ground - not very safe, but it works. The on-switch is a pain, but as someone else noted, you can pop an O-Ring around the Finder's power button to make it harder to activate in your tool bag. A rubber band works too.
