How to find a break in an invisible dog fence

Step 5 Find the break

Walk the perimeter while passing the radio antenna over the ground where you suspect the wire to be. You should be able to pick up a clear, definite signal. The video shows me walking the radio back and forth over the line (in reality the signal was much clearer than it sounds, but you can definitely get the idea). When tuned in perfectly, the signal sounded like a rapid tapping/beeping - when tuned close but not right on, the signal caused the static to get louder as the radio passed over the wire. When you find an area where the signal drops out for a few feet, this is likely to be your break. Go slow and check the whole perimeter before you start digging, I found areas that seemed weak but when I eventually found the break it was pretty obvious.
