Product Description

The Pet Fence Wire Break Locator makes finding breaks quick and easy. Often times, it is not possible to tell where your wire is broken unless you have the wire break locator.

It's not uncommon that you would need to dig up all your wire to find it. The Wire Break Locator will help you troubleshoot your system if there is a wire break indication on the fence transmitter or if the receiver collar is not functioning on the containment system but works during the short loop test.

Our Pet Fence Wire Break Detector can be used for any brand of underground pet fence to find wire breaks. This new and improved system replaces RFA-50.


  • Find wire breaks quickly and easily
  • Eliminates need to re-wire your yard
  • Dig up the wire where the break is - not all the wire!


  • Wire break location transmitter
  • Receiver with expandable handle
  • 50 feet of Boundary Wire

  • 4 gel-filled capsules
  • 4 wire nuts
  • 2 cable ties
  • Receiver requires 2 AAA batteries - Not Included
  • Owners Manual

The wire break locator is not returnable unless it is defective. All returned wire break detectors will be tested for proper operation. We will replace defective wire locators at no charge.

  1. Really works! 5 Star Review

    Posted by on Mar 19th 2012

    I was very skeptical about this device, but it is worth every penny. We were able to pinpoint within a couple feet of the break and fix it quickly.

  2. Great Purchase 5 Star Review

    Posted by on Mar 5th 2012

    We purchased the break detector and I found the bresk in the wire in about 45 min. Also found a weak spot. We have about 4 acres fenced. Last time I spent 2 days jumping wires and spliceing to find the break.

  3. Break finder for the invisible fence. 4 Star Review

    Posted by on Mar 5th 2012

    We live on 5 acres and have the invisible fence enclosing the large area immediately surrounding the house and barn area. The unit went bad during the winter and we were having a hard time finding the wire in 2 feet of snow that was covering the area. The broken wire finder worked wonderful. We found the break within an hour in one of the buried areas in the frozen ground. We have made temporary repairs until we are able to replace the section that was broken. It was interesting to note that the dogs did not even realize that the fence was not working. They never left the area where they knew the fence to be. We love the fence. Thanks to our son who had the original one and we saw how well it worked when our dogs had to stay at his house for two months while my husband was very ill.

  4. Worked like a charm on nearly 3 acres . 4 Star Review

    Posted by on Feb 3rd 2012

    The only downside to this product is that you have to be on your habds and kness crawling along the preimeter, so that the radio signal can be detected. For us it was a long crawl abt 3 acres under fence, but it's been there 5 yrs and this winter was the first problem. Unfortunately, for us we started at box and followed around and the break was at the end of the line , almost back at the box. Oh well, it still was found. Poor son, was frostbitten and had some sore knees but hey the dog is safe again ! LOL! Thanks for the product, as we both have your fences, and both live in the country , it will be handy to have.

  6. Super Product - Beats laying a new wire! 5 Star Review

    Posted by on Jan 23rd 2012

    This is a good product. When I opened it, I was impressed with how massive the device was. It is much larger and heavier than the radio fence control!

    Best of all though - it worked! I found the break in my wire in about 10 minutes. Sure beats burying a new wire!

    The only thing that I think could be improved is that the two radio tones broadcast through the two wire ends are somewhat hard to distinguish at first. It took a couple of walks around the yard to figure out what I was listening for.

  7. Works well, better than expected 4 Star Review

    Posted by on Jan 23rd 2012

    I hooked it up and it worked well. This particular fence has a 700 foot loop, so the signal got a bit weak toward the turnback point. Part of this fence is under water, and the receiver picked up the signal just like the part that is buried in dirt.

  8. A needed accessory 5 Star Review

    Posted by on Jan 5th 2012

    Useful for locating broken wire

  9. Well worth having... 5 Star Review

    Posted by on Dec 22nd 2011

    The underground radio fence break finder was a huge timesaver for us. It worked well to find the break quickly so our dogs are safe again! Our fence is around 4 acres through prairie, bramble & woods. Installing a new wire or finding the break without this device would have been a huge task. Our break was located and the wire was repaired in a short time. Thanks once again Radio Fence Co.!!!

  10. Worked wonderfully! 4 Star Review

    Posted by on Dec 20th 2011

    After installing detector it took about 5 minutes to find break. I can only imagine how look it would have taken with out this device.
