Does "non-contact" mean I can use it to find a break in a wire (an "invisible fence" for dogs) by tracing the path of the wire with it?

Non-contact sensing provides an indication of the presence of voltage, typically around an electrical outlet. My experience with NCV testing, however, is that it rarely provides a reading unless current is flowing (i.e., something is plugged in and operating), in which case you know there's power anyway without the tester. In your specific example, if there's a break in the "invisible fence" wiring, there's probably no current flowing, and you'd be lucky to get a clue. Since the tester must be very close to the wiring, and yours is buried, that's a second strike. It may work, but I wouldn't bet on it. There are cheap standalone NCV testers that you may want to try before buying a more costly multimeter that happens to include the feature.

If your wires are in wire harness and bundled up, then I'm going to say no. This may be good for tracing wires but not good for finding open circuit because the transmitter is too strong. I would not recommend this one.

You do have to be pretty close to the wire for the sensor to pick it up, so I don't think it would detect it at all underground. Besides that, even if it could, it's not designed to clarify where an abrupt end to a signal is, so if you lost the signal, it could mean the wire is broke or you are no longer following the wire. Bottom line, this tool is not the way to resolve your problem.

I think that it would work fine. Instead of a intermittent light with each pulse it would glow continuous but would still indicate your fence was working.

They have to make contact. I'm not sure how you could use it on a fence, but that doesn't mean it can't be done.

I'm no electrician, but doubt this would work - the wire needs to be suspended by insulators, which is accomplished by the plastic poles in the kit. If you ran the wire along the bottom of a fence, it would likely contact the ground and complete the electrical arc by that means, rather than through the dog. I suppose it's possible that the wood could act as an insulator without grounding out, but you would have to install it carefully - and any time the wood became wet, it would not act as an insulator. Why can't you instead run the wire on the poles a couple of inches inside the fence, 6" up from the ground? I would think that would work fine. The shock amount is certainly enought to discourage a medium dog.

That's kind of the idea of it - to keep dogs out of a circular area around the rock. It's won't work as a fence to keep dogs IN that circle, only out of it. How well it works as a fence to keep your dog out of the circle depends on your dog, whether he or she is already trained with an electric collar, and how much he or she cares about the beeps & small shocks. It won't work as well as a real solid fence, but my dog (who was already trained to our underground fence) gives the rock a wide berth, even if her toys get close to it. She'll wait as I go inside the circle and get the toys for her, because she does not like the shock and she knows how to avoid getting it.

It depends on how deep it is buried. These devices are normally used to pick out a single cable from a bundle of wires. You may be better off with a metal detector.

You can't cut the wire and attach it to the fence. The fence won't transmit the signal.

It's designed for tracing wire . If one side is grounded trace the otherside. For your purposes turn breaker off disconnect wires at both ends, measure the short with a volt ohm metercut ohms in half and multiply by 12 or 14. With a 12 ohm loop divided by 2 is six ohm s times as equals 72 feet. This changes with the gauge of wire. Then trace with one lead frthe toner to earth ground the other to the wire. Or, you could buy a ground fault meter. This is the best I can come up with for these tools.

Hello, I have no idea, was just curious about the item and thought I could use it to possibly track down a wall switch that goes nowhere in our house. turn off all breakers but the circuit the switch is on and check for a signal thru the wall with the switch on and follow it, have not tried yet. Just checked around a few wires and it does sense the electricity. I think the deal on it detecting cameras is that you can see the infrared with it or something. Have not had time to really check, it may just be a barely useful gimmick. But I hope I can trace the wire. It may make a cool kinda selective sensitivity signal tracer.Peace!

Yes. I use this device to find a break in my electric dog fence which uses low voltage.

I bought the wire but didn't connect it because we had to run it across the driveway and my husband had to move it when snow blowing. We purchased a pet safe correction collar for our golden and it works, in our opinion, better than the fence.

I used it for splicing underground dog fencing. I'm not sure if the "brand" is Invisible fence but yes that's how I used them.

I used this wire for an electronic dog fence. It is buried in my yard and has not been harmed by any of the elements.

Definatly, this works very well at finding metal. It does not work so well at detecting the DIFFERANCE between metals. We normally find old steel nails even just tiny rusted pieces of them as far as 6" below compact ground. My guess is you will be looking for steel posts just under the leaves, the key is you will need to pass the detector DIRECTLY OVER THE post you are looking for. Its not going to tell you "if your close", a metal object on the ground within an inch of the outer ring will not set it off it must pass over the object to set it off. Hope this helps

Most of the major electric dog fence manufacturers recommend that you use the same gauge wire around your entire loop (ie perimeter) to ensure a consistent signal. So if your Invisible Fence Brand wire is 20 gauge then it will work with the PetSafe 20 gauge wire. I'm not 100% sure but I think Invisible Fence Brand uses either 16 or 14 gauge wire and if that's the case, you'd be better off matching the wire you buy to repair your break with whatever gauge you're already using.
