NOYAFA NF-826 Underground Cable Locator Wire Tracker, for Dog Fence Cables Irrigation. Wall and Underground Pipeline Wire Detector. Test Short Circuit Breaker of Wall and Underground Cables.

Relatively inexpensive, buy does exactly what it says it will. Used this to trace buried telephone wire that carries the copper wire DSL internet----we aren't in a service area for anything else. Did have to open the "telephone company" side of the house box to see which were the powered and grounded wires and attack the leads. Also used it to trace the electric power utility buried lines (120 V) buried to house, barn, and well pump house. Again, some knowledge of what to connect the device lead clips to in the electric panel is required, but very simple and the built in voltage tester make that easy. Signal receiver worked well, even at 100+ yards from the transmitter. Saved me a lot of time and money.

I purchased a home 14 yrs ago and have been looking for my sprinkler valves ever since. I was skeptical about making this purchase based on some of the reviews. This tool works! It took some trial and error but once I had a good understanding on how to use it (about 2 hours of fiddling arourd in my yard), it was just a matter of minutes before I located the valves. They were buried in my flower bed about 18 to 20 inches deep under a rose bush..

I bought this because of all the issues I had with the tethered device types. It's a bit more expensive but it does a much better job. I needed it soon after I bought it, but it will take some time to learn how to use it effectively. I didn't find the spot where a squirrel had mostly chewed through. The signal strength tapered so slowly that it wasn't until I replaced a few 100' long section that I discovered this. Looking back, I think it might have been telling me it but I missed it.

FAR exceeded my expectations! I first tried one of the less expensive devices, and it was useless. This one worked right out of the box, and made it downright simple to trace the buried wiring for several circuits over a distance of hundreds of feet. I can locate the conduits to within about 6". I also used it to find a break in an underground wire, to trace a buried plastic sprinkler pipe (by passing a wire through the pipe), and to trace wiring for one specific circuit inside my house. It worked beautifully in all cases.

The media could not be loaded. This detector worked great for me. I had some doubts about this but decided to take a chance. This turned out to be exactly what I needed. I had been trying to find the end of a 2" PVC buried drain pipe (AC condensate drain) in the back yard for several days . I did a lot of useless digging but found nothing but dirt. I bought the detector as a last resort. After playing around with it a bit I connected a two conductor 16 ga wire to the end of a fish tape with the end shorted together and pushed it through the end of the pipe at the AC unit I connected the transmitter unit to the free end a powered it up. I heard the signal blaring immediately and started tracking along the garage floor and then outside in the yard. I attached some pics and a video. This thing saved the day. Wish I had it to start with, I could have saved a lot of sweat.

Works pretty good, but won't show a short to ground unless the wire is completely broken. Will not show a short to ground that is tripping a GFI unless the wire is completely burned to open circuit

Indispensable for locating lines inside our house. I had multiple mystery switches in the garage leading somewhere. I hooked this up and toned the line through the wall to find the termination (outside lights). Made the job simple for electrical work. Also used it to identify ends on conduit lines I pulled after the line tags fell off. I haven't used it for chasing plumbing down but I read in the manual that is another function.

Transmitter will not charge. No way to contact Seller directly. The Amazon assistant does not give an option for defective, only damaged which pushes it to Amazon support, who will not assist since they only did fulfillment.
