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.

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

Works amazingly well! Found a gas line by the tracer wire that was deeper than 3 feet down. Successfully traced it over 1000 feet along the line. I was truly shocked by the accuracy of this tool.

Purchased this product to help me trace my underground dog wiring and help me find the break. They were useless! Signal didn’t discriminate were the wiring was let alone where the break was. Waste of money!

Not working in underground cable

Does what it claims. I located an important TV Trunk cable in no time at all. Clamped on to the outer shield of the Trunk and earthed the other with earth stake and was able to trace cable thru 2 completely covered pits a total of about 600 meters. Add TV cable locating to its list of uses!

Bisher eine durchweg positive Überraschung. Zum Finden von Unterbrechungen des Begrenzungskabels beim Rasenroboter habe ich bereits vor zwei Jahren ein ähnliches Gerät (häufig zu sehen bei den YT-Videos) gekauft, das preislich aber weit unterhalb angesiedelt ist (unter 20€). Da die Performance eher mäßig war (Handling & Suchleistung) und der Empfänger nach insgesamt nur zweimaliger Nutzung gar nicht mehr funktioniert (Gerät lagerte mit entnommer Batterie) habe ich mich nun für die teurere Lösung entschieden. Ich bin tatsächlich begeistert - kein Vergleich zu dem Billig-Gerät - dieses ist um Klassen besser ! Im Detail: Das Gerät kam tatsächlich einen Tag nach Bestellung an, in der üblichen Tasche. Das Zubehör ist recht reichhaltig, inkl. deutscher Anleitung (die ist sogar recht gut geschrieben, ist keine hirnlose Übersetzung). Alles macht einen recht wertigen und durchdachten Eindruck, die Akkus sind vorgeladen. Die Arbeitsleistung des Geräts ist tadellos und beeindruckend. Das Finden der Bruchstellen war buchstäblich in Sekunden erledigt, obwohl deutlich über 100m recht weit weg und vergleichsweise tief im Boden. Das Ansprechen war so präzise auch Dank der variablen Sende- und Sucheinstellung, dass die Lokalisierung auf wenige Zentimeter genau möglich war - das erspart unnötiges Graben. Zusammenfassend gesagt: Der hohe Kaufpreis (im Vergleich mit anderen Produkten am Markt) mag abschrecken, aber Stand jetzt ist es jeden Cent wert. Ich hoffe, dass das Gerät lange hält und ich keine nachträgliche Abwertung vornehmen muss. Bisher ist es eine klare Kaufempfehlung - auch zu diesem Preis.

Parfait pour détecter une coupure de fil souterrain de guidage pour robot tondeuse. A condition de pouvoir connecter une extrémité à l'appareil émetteur. Beau matériel, manuel traduit en Français presque intelligible.

Alors contrairement à certains commentaires, il y'a bien une notice en français et le câble d'alimentation est fourni. J'ai utilisé ce produit afin de retrouver un câble d'alimentation de portail électrique enterré à environ 30 cm sous terre. La détection est précise, l'intensité du signal n'est pas seulement sonore mais aussi chiffrée de 0 à 250 ce qui facilite beaucoup la localisation et de rapidement suivre les virages pris par le câble. En même pas 5 minutes, j'ai pu me rendre compte que contrairement à ce que je pensais, mon câble d'alimentation n'arrivait pas dans mon garage mais dans une boite de dérivation dans mon salon. Petite remarque tout de même mais qui est liée à la technologie utilisée, l'appareil est perturbé par tout ce qui est métallique, la distance de détection s'effondre alors du fait de la perturbation électro-magnétique de ces pièces.
