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

    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 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.

    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.

    Cant even accurately locate a wire above ground consistently. Absolute junk. Not even worth 1-star. Retiring asap.

    Easy to set up and use. Easily found the breaks in our underground wire for an easy fix. 100x better than the useless cheap one I bought last year. Sounds make it clear when you are over the wire. Just go slow.

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.
