How to Locate Buried Invisible Fencing

Quck answer

To find buried invisible fencing, follow these steps:

1. Determine the approximate location of the buried wire by referring to the installation manual or contacting the manufacturer.

2. Use a metal detector specifically designed for locating buried wires. Start at one end of the wire and slowly move the detector along the ground, following the wire’s path.

3. If the metal detector indicates a signal, mark the spot with a flag or any visible marker.

4. Repeat this process along the entire length of the wire until you have marked all the spots.

5. Once all the spots are marked, you can dig carefully to expose the wire and make any necessary repairs or adjustments.

Remember to always exercise caution when digging to avoid damaging the wire or any other underground utilities.


An invisible fence is a type of fence that keeps pets confined within a designated area. When a family moves, they often leave the existing invisible fence wiring and install new wiring at their new home. This means that the new owners may already have the wiring for an invisible fence. If you have recently purchased a home with an invisible fence, you can use a portable AM radio to locate the perimeter of the fence.

Step 1

Ensure that your invisible fence is plugged in and turned on. Look for an indicator light on the radio transmitter unit to confirm this.

Step 2

Determine the radio frequency used by your invisible fence. Typically, this is an AM frequency towards the lower end of the spectrum. Refer to your fence instructions for the specific frequency. If the instructions are not available, turn on a portable AM radio near the fence transmitter. Scan through the AM stations until you find the correct one. You will know it is the correct frequency when you hear a rapid clicking or beeping sound.

Step 3

Walk around your yard with the AM radio tuned to the correct frequency. Begin along the perimeter, as this is where the invisible fencing is most likely to be located. It is also helpful to crisscross the yard to detect any other invisible fencing that may be surrounding a specific area. Any areas where you hear a quick tapping or beeping sound from the AM radio indicate the presence of invisible fencing.
