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.
