    I tried following the cable from where it starts but signal was not distinct so I went to where I know the cable goes and dug it up. It is about 10” deep. Once uncovered it sensed the signal but would not sense it where the cable is buried. A waste of time.

    We found the break in the invisible fence and fixed it ourselves. The fence company could not give us a date to check it for over a month. Their loss.

    This was well worth buying. I used it to find multiple breaks in my invisible dog fence. It doesn’t point you to the exact spot of the break, but the noise gets very weak and dies a couple of yards before the break. Good enough to help you find the line and then carefully dig along it until you find where it broke. I have 15 acres, and the signal got very weak the further along I went, but it almost made it half of the perimeter. Very pleased. I also liked that this model didn’t have the rechargeable battery. I hope I won’t need it again for a while, and a rechargeable battery could be useless after a couple of years with no charging.

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.
