Underground Wire Locator Upgrade, RockyMars Cable Tester for Invisible Fence for Dogs, Circuit Breaker Finder, Electric Fence Wire Tracer, Wire Break Locator, etc.

I bought this to find the breaks in my wire pet fence. While it did accurately find the wire which was buried up to 5 inches deep it did not find the break. It kept reading a strong signal after the break. This may have been something I was doing incorrectly but I followed the instructions carefully. I was able to fix the wire but only by digging 5 holes and measuring continuity test between different points of the wire and then running a new wire between the points I found a break.

Helped us find a break in our underground fence in just a few minutes. Very useful!

We have an invisible fence for our dogs around our 4.5 acre property. The loop detector was showing a broken wire, so I bought this to trace the break. The perimeter of the property is around 2000 feet, so I thought this would be the ticket to find where the break was located. The good news: I found the break. The bad news: the distance this will give a clear signal is around 700 feet. After that, the signal is too faint to detect. I was able to finds the original splices in the wire and dig them up to attach the transmitter. That allowed me to continue tracing until the break was found. For most properties, this would probably work great. For larger properties, you will not be able to attach at the source and trace the whole length.

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

Instructions were great and easy to follow. We purchased to trace irrigation control valve wires that are 18-24” below grade. The sensor was not able to find 80% of our wiring.

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.

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.

Took a little time to figure it out but ended up narrowing down 3000 ft of wire to a ten foot section and found break. Did it in about an hour and a half.

This thing found a break in my guidewire for my Landroid in 2 min, which would have taken me hours to find.

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.
