Can you use this to trace the outlet to its circuit breaker if the circuit breaker is damaged or off?
I have outlets wired in series: some NM. some metal-shielded. Can I detect signal in accessible wires "halfway" to the breaker to confirm route??
Can this trace a wire routing through the wall.
can it be used to test another outlet to see if it's using the same line/breaker?

Superb tool for solving basic home wiring issues

This has helped me unravel the mysteries of my house wiring. You plug the transmitter end into an outlet (three prong) and go hunting for the right breaker with the sniffer. You can buy adapters to plug into light sockets and even alligator clips to attach the transmitter to bare wires if you are feeling bold.The tool has a sensitivity knob on the sniffer. This is the part that you get a feel for when using the tool. If you have the sensitivity too high, it's difficult to identify the exact right breaker within the breaker panel. The trick is to lower the sensitivity while you are sniffing until it only beeps when you hover over a single breaker. Bear in mind there is a proper orientation indicated on the end of the sniffer.Now I have one of these, I wouldn't be without it. It's really useful and as you get better with it, you can use it for tracing wires and all sorts of things to get you out of a bind. Highly recommended.

Works very well, but you have to fiddle with it a little to get it dialed in.

I had no idea this kind of product existed until I was having trouble tracing circuits in my house. The house is midcentury, so not crazy old, but it has had some interesting wiring work done over the years. During those years nobody has apparently taken the time to accurately label the breaker boxes downstairs, so you can never tell what circuit anything is on.Normally this is frustrating, but not the end of the world, but recently was a much bigger problem. I got a MIG welder that I can use for hobby stuff, but it has to be on a 20AMP circuit instead of 15AMP. Normally this wouldn't be an issue, just double check it is on a 20AMP circuit and that the outlet is also rated 20AMP, but of course I couldn't tell which outlet was on which circuit.I didn't want to have to guess or start flipping breakers to see what turns off, so I looked online. I was originally just hoping for a test plug that could give me some sort of further information. I already have the ones that just tell you if the outlet is wired correctly. I was SO pumped when I found out this thing existed and wasn't crazy expensive. I couldn't wait for it to get here.I tried it out and I was able to quickly make sure the outlets, including GFI, were wired correctly (because the plug section also performs this function) and which circuit they were on. It saved so much time and messing around and gives me a great option for future situations that are similar. I have even already lent it to a couple of friends who didn't know this technology existed and were also very excited to make use of it.Using the tester can be a little delicate, but I did look at some other reviews that were helpful. Basically you start by plugging in the dongle to the outlet you want to find the breaker for, then you start sliding the handle along with the tip making contact along the center of each circuit breaker. Then you keep turning down the sensitivity until it only beeps on one breaker switch and that is the loop that the plug is attached to. When it gets the test signal from the plug, the handle frantically but rhythmically beeps. It takes a few tries to recognize it, but it is a distinct sound.The sensitivity adjustment has to happen every time you use it, as far as I can tell, but after the first time it is much easier because you know what to listen for.

Works through walls too

I just bought this to use in my older house and it has worked great for finding the breakers and even wires in the wall! I find for the walls it can be a little hard to trace as I feel like the wires have to be within 1-1.5" deep with the sensitivity maxed out and you can loose the signal being as little as 1/4" off from the trail, but it totally works and let me trace a few wonky paths so I could figure out exactly where the wire was moving in my walls and even to a buried junction box.I also really like the manual adjustment since it lets me hone in the breaker real quick and I don't have to scan the breaker like you see with the auto-adjusting ones. I just go to the breaker on about "half" sensitivity, move fast, and when I hear the beep I just drop it to lowest immediately and find it every time. Also due to the manual aspect of it, it let me figure out that a circuit was being served by 2 breakers and tracing which wire went where within the 14/3 wire sleeve itself since I could turn the sensitivity down so low. The socket tester works well too from the few tries.Only real issue I noticed is if you have any of the circuit based dimmers that basically everyone uses now since LED lights need them for dimming, it'll also send a signal in the line that this can pick up. It's real obvious though as it beeps much faster and sounds funny compared to how the device normally works, so either just ignore it and follow the normal beeps or turn off the light, surge protector, etc.Great device and wish I had one sooner to figure out all this weird wiring and no constant breaker switching either!
