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 don't have a locator wire on my galvanized water pipes, and unfortunately, a pipe sheared off in an area that would cost thousands of dollars to open up and fix. So I wanted to trace the pipe with this locator. I pushed the included ground rod into the moist sand near the pipe, clamped the black clamp to the ground and the red clamp to the pipe itself (used sandpaper to ensure a good connection). I turned on the transmitter, pressed the transmit button, then walked around using the receiver to try to find where the pipe went. Nope—didn't work at all. I was disappointed and considered returning it. I then looked over the settings of the transmitter itself and noticed it had a code set button. What are these mysterious codes, you ask? I searched the manual and was still dumbfounded because I didn't find a single reference to what that code set button did. I suspect it sends out a different type of signal—different frequency, different waveform, etc.—because once I changed the code from A to E, Bob's your uncle, the receiver started beeping like a Star Wars robot, telling me where the pipe was. I found that when the pipe is over 3 ft deep, the number displayed will be something like 59, and moving to the left or right, this number will drop, and there is a change in tone. It was well worth the price to me; I just wish they had a better manual.

Impressive tool. Just know you must watch the bars on the screen while listening to the sound to pin point the location of the underground wire.

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...

This is actually a great product for the price. I needed to find my sprinkler wires and this worked like I hoped it would. The noise it makes is very irritating but I can deal with it. Read the directions and practice with an extension cord.

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

I am searching for the phone line that comes up my 500 foot driveway in a rural setting to put in a sewer line that will go right over / under the phone / DSL line. At first I connected the leads to the 2 active lines. The receiver registered 53 volts. First good sign since phone lines have voltage and I was worried I might burn out the unit, which it did not. It signal only went out about 5 feet. I then connected to one active line and the ground. That turned out to be the correct connection; don't forget to turn the transmitter to transmit since turning it on does not automatically start transmitting. The user manual has lots of examples but being new to this, I wasn't sure which connection to use. The receiver comes on in AUTO mode, the most sensitive setting. It was so powerful, I stood there with the receiver at waist height and could follow the line at a walking pace. When I got to the spot where the sewer line was going to cross, about 250 feet from the transmitter, I put the receiver in the least sensitive setting by putting the receiver in manual and pressing the down arrow several times. Even at the lowest setting it still picked up the signal loud and clear. I then got on my knees and swept back and forth until I found the line and started digging. As I dug down, I used the unit to pin point if I was getting close. I did not want to cut the line so I was very cautious while digging with the shovel, even though in my area, the phone line is in a metal conduit. Just for fun, I even used the unit to find where my sprinkler values were buried. Overall, this unit is very impressive. I read several reviews of cheaper units where there were complaints of poor user manuals and weak signal. This unit is powerful and the user manual is very extensive... almost too extensive, but I would rather it be very detailed when I use it for more complex projects. Also note that when I first connected the unit to the phone line, I disconnected the modem thinking the transmitter signal would damage the modem / router. It started raining so I disconnected the unit and put the modem back online and had to continue later. When I went back out to continue hunting, I forgot to disconnect the modem. I finished flagging the spot and remembered the modem. It didn’t do anything to it and my internet service is working normally. I don’t know enough of the technical details of the transmitter to know if it could damage a modem / router, but in my case, it did not.

Waste of time and money. It does not work in any meaningful way. Yes, it will makes noise but the signal will jump from target conductor to another one running along the same path. Impossible to pinpoint anything.

This thing saved me so much time, it worked perfectly as described

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.

Allora lo strumento funziona bene e secondo me è l’unica cosa che può aiutare veramente nel caso in cui abbiate un cavo perimetrale di un rasa erba in quanto ho scoperto che dopo tre anni circa comincia ad ossidarsi a caso lungo il percorso, quindi con il tester risulta la continuità però grazie a questo strumento si vede che il segnale diminuisce drasticamente nel mio caso da 250 a 50 circa cosa che fa uscire rasa erba oppure dopo un po’ crea l’errore cavo interrotto che non fa più partire il robot e si diventa matti a capire dove si è tagliato nel mio caso infatti non era tagliato ma soltanto ossidato e l’ho scoperto tramite il naso elettronico, tirando su il cavo e piegandolo leggermente si è rotto come un grissinopoi ho sostituito uno spezzone di filo e tutto ripreso a funzionare . Ho provato a fare il primo video portate pazienza se la qualità fosse scarsa.😅😂
