NOYAFA NF-826 Underground Cable Locator Wire Tracker, for Dog Fence Cables Irrigation, Wall and Underground Pipeline Wire Detector, Advanced Circuit Breaker Finder for Wall and Underground Cables

I was skeptical because it wasn't one of the more well-known brands. But for a residential user trying to track down one short in a wall, this worked OUTSTANDING for me and the price was right. It saved me dozens of hours and worked great! I would recommend this to any occasional user. It was way cheaper than calling an electrician! Bravo Noyafa!

works great , I only quickly tried this out and it worked great , I have 7 underground power lines each in 2 inch plastic conduits , I need to locate these lines before digging started on my property . I called two different private locating companies , I had quotes from 225.00 to 400.00 , this purchase saved me quite a large amount , and I can use it when ever I have time and I own it . This is another one of the great products that Amazon sells . Thank You ,,,

This system does work quite well, and worth it for repairing our dog fence. A few things I figured out helped me a lot to use it. 1. Read the manual. I do have some experience with electronics, but I did find the diagrams to be a little small to see clearly. The text we pretty good, however. 2. The quity of the electrical connection to the buried wire is critical to its operation. Can't say this enough. Sloppy or loose connections won't do! The alligator clips supplied are suprisingly good quality, but even so, just wiggling the clip connection produced a wide range of signal quality. My fix was to eliminate the supplied alligator clips and cables, and just make short adapter wires with banana plugs to plug directly into the source device and the system ground and the two fence wires where they connect to the control box. So much better!! You can buy banna plugs for a few $ on Amazon, Parts Express, etc. I had a few false starts until I did this. 3. I plugged the transmitter into a charger to be sure I always had a strong signal. Set the output to its maximum, and start the transmitter (there are two actions, one to turn on power, and one to transmit!) 4. Tape the receiver to a piece of wood, broomstick, etc. so you can walk with it and keep the antenna very close to the ground. The Antenna 'snout' seems to most sensitive in the direction its pointed, so point it at the ground, don't waive it in the air. For precisse location, point it vertically at the ground. The signal strength meter and audio DOES work well, and it reads highest when nearerst the wire underground. 5. Keep the sensitivity on the receiver just high enough to receive the signal reliably. This is the most accurate. If you are searching for something when you have no idea where to start, then increase the sensitivity. 6. First, check that the pair of wires leading from the control box to the perimter re intact. To do this,connect the source to one of the wires leaving the control box (and the ground of course), and trace the wire to the fence perimeter looking for breaks. If none are found, THEN connect the device to the OTHER wire and check that. For me, these wires were intact and I could see that one went right, and one went left around the yard. Start nearest the source - If you can see the wire exit the house, start there. The receiver would be responding strongly there, if it isn't, stop and check the connections and that the transmitter is transmitting. 7. I decided to keep them both connected, and traced the wire's path around the yard. If there was only one break, I would not have detected it, as I have the transmitter conncted to both ends of the loop (so both sides of the break would have had a signal). If that happened, I would have just connected the transmitter to one of the loop wires and started again. I know we had or yard aerated twice, so I guessed there might have been more than one break so I just made my way around the loop. 8. I detected and located one break with this setup (both wires powered), which meant thatere must be another! So I apprached the area from the other side where I had signal and found another dead spot, indicating a break. The two breaks were about 20 ft apart and under our garden (hmmm..). We decided to re-route the wire in this area, as we put in a larger garden, so the repair was straightforward using some new 14 gage stranded wire and waterproof wire nuts. Total detection time was about an hour including making come test cables. Next project is figuring our where some wires go in our house...

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.. Power went out in several rooms in my home. I determined I had an open neutral. After ruling out a loose connection or a bad outlet/ switch I used the tracer to find a break in a neutral wire behind the wall. Again, it took some time and research but once I had an understanding of how to approach using this tool it pinpointed the broken wire

What a great tool. Works as advertised. I had it up and running in about 10 minutes. Traced out a line buried in my front garden bed. Great value for money saved me calling out a private service. I knew where it ran (the bed) but not the location. This tool did the job. The only thing I was curious about was could I use it in a live circuit. I decided to play it safe and shut the breaker down 100A feed to a sub panel.

I purchased this because my SportDog invisible fence was showing a break in the line- I was unaware that both that line and the Invisible Fence wire require a specialized locator that can detect radio signals, so when I used this product I was getting positive signals for power through the entirety of the line that's around my acre property. I finally called SportDog for info, and they let me know that even their specialized locator would not necessarily detect a break in the insulation ,which is enough to shut down the loop (I was not able to find any breaks in the insulation). They recommended installing a new perimeter wire. As to this product's performance- even though I adjusted sensitivity to the highest level, I had to constantly move the transmitter as I was only getting a positive reading for about 3 feet on either side of the transmitter so it took me forever to get around the yard and I kept having to dig up the wire to connect to it.

This tool works fantastic, I used it to find a break in a underground pet fence. It does exactly what it says it can do and more.

I ordered a new item and received an obviously used product. It had scratches on the back of one. The probes were wrapped. The screens were dirty. I will return it as I don’t intend to pay a new price for a used product.
