    I was leery after reading the negative review. I needed to find one end of my invisible dog fence wire at the far end of my property where I know the wire is broken. A tree went down in the winter, roots pulled up the wire, and then I hit the wire with the mower in the spring. I found one end but couldnt find the other. I dug and dug trenches all over to no avail. Rented a metal detector but it didnt pick up copper. Ordered this wire locator in desperation. I found the wire end within 10 minutes. Whoever posted the negative review saying no signal after 200 feet clearly did something wrong. My wire break was 1000 feet from the invisible fence transmitter and this thing found it with ease. My wire is only 1-2 deep in the ground. I duno if this will go 2500 feet as advertised, but it made 1000 feet with ease. For a cheap wire locator from China, this is pretty darned good. Better than paying $600 for a Greenlee/Tempo cable locator. Definitely recommend it and will look out for other Rocky Mars / Noyafa products when need.

    Locating under ground dog fence. Cheap design with transmitter, wire and sensor that pendulums across ground breaks. Solder eventually separates. Wand style would be more durable.

    After 24 years of service our underground dog wire for electronic fence had to be replaced. There was one section underneath the driveway that had to be spliced, as it was blacktopped after the fence was put in. Initially we could not find it but with the help of this product we did. My husband said it was worth purchasing it for this alone. Im sure there are many other applications also.

    Had a perimeter wire broken in 3 different places and this guy detected them all without issues.

    The unit worked perfect . My only issue was trying to get the transmitter battery cover on.

    We had a break in the invisible fence for our dogs and would have cost about $150.00 to have repaired. I went on line and purchased the wire locator and was able to find and repair the broken line. Saved us nearly $100.00.

    I purchased this product to locate a break in my invisible fence for my dog. This system will not locate the wire past about 250 linear feet. The audio signal gets very weak and becomes impossible to hear. I dont know whether this particular system is faulty or the product will not perform as advertised, but I am very disappointed.

    I have a 1 acre lot with approximately 1000 feet of wire. This tool helped me find an intermittent break in my underground dog fence. I was paying another company 150.00/ visit every time it needed fixed. The issue ended up being one of their old splices that was coming apart. Now that I have this tool, I will never pay for that service again.

RockyMars NF-816 underground wire locator is designed to allow the user to track low voltage cables used for garden and landscape automatic watering systems, and also low voltage garden lighting systems. It can also be used to trace other metal cables. The system uses a "transmitter” to send a signal down the cable beingtraced or to a solenoid valve that is being located. A "receiver" is then used to pick up the signal and follow the cable or locate the coil.
