When I found out that the electronic underground fence was broken, I called a couple of the installers to get a price on repair. Because of all the snow that we accumulated and the zero degree temps, the price for repair was going to be about $160 to $170 if they can find the break within 30 minutes. I decided to purchase the Kolsol F02 Wire Locator. After receiving the unit, I followed the directions and found the break in an area where it's not traveled (way back in the woods). I dug up the two ends of the broken wire, repaired it and saved over $120, and I still have the unit. Worked out great.

Worked well to find a break in my underground dog fence

Need video to know how to operate and to know what sound it makes when it finds a break.mefd
