worked great, 4/22/14
I tried getting the cheap choke and doing the home made trick, but that didn't work. I was reluctant to spend the money for this, but I did not want to start diggin up the whole line. The locator found each break quite easily. Turns out my neighbor had aerated a bit onto my lawn, cutting the wire in a bunch of places. The signal was quite strong, and pin-pointed each location to within a few inches. Nice that it came with extra wire and splice kits. I was back up and running shortly. A bit pricey, but worth it for me.

This product does work!!, 4/17/14
Ran over my yard with an aerator, hoping to miss the wire.....guess what, hit it somewhere. No chance in finding it manually, but did a search and came up with the solution of using the Wire Break Locator. I was skeptical, but had no choice. Once the unit was received, I did the assembly, took all transmitters outside, hooked everything up, and in 15 minutes found the break, and fixed it. No problem! Follow the instructions! If you lose the signal completely, you now have 2 breaks. Fix the one you found, and move on, or go at it from the other end. One direction has a intermittent tone, the other a solid tone, easy to hear, easy to figure out which is which. Think through how this works and you will understand the process, it's easy!

No DC power supply, 4/11/14
I was sorely disappointed in this kit. When I needed to use it I had everything in place and realized the DC power supply is not included and must now or it to find the break in the line. If you are going to sell a kit sell the entire kit.

very disappointed in overall process, tech support, and refund policy., 8/15/13
First, I readily admit that the product did emit "beeps" when near the wire. The problem, however, was the cheap AM radio that comes with the product. Instead of locating the "break" in the wire, I did not receive a "break" from listening to Rush Limbaugh pontificate during the whole exercise in futility. We live in a rural area, but Rush Limbaugh still dominated the AM dial. I was informed by customer support to try either again either early a.m. or late p.m. to try to achieve pure static. No such luck.

RFA-450 Wire Break Locator - Great Product!, 7/17/13
Our in-ground fence had a break in the wire. The lot is approximately 2/3 acre so it was a challenge to locate the break. I purchased the wire break locator and had the break repaired very quickly. It was a simple matter to install two ground wires and connect the perimeter wires to the supplied transmitter. The receiver emitted a strong tone which made it easy to locate the exact spot of the wire break. I was skeptical of this product before ordering it but after using it I would highly recommend it.
