Review on Efficiently Detect Wire Breaks in Any In-Ground Pet Fence with PetSafe Wire Break Locator from Parent Company of Invisible Fence Brand - Repair and Reconnect Wire Components Included by Jennifer Franks

Really well designed product from packaging to use. Break found quickly. The red and green LEDs reliably indicate 1. whether you have a break and 2. where to find it. (or you). Found a wire break caused by fast growing tree roots. My wire forms the boundary for the robotic lawnmower. A NOTICE. This product is intended for use with a dead line because you must connect the product's transmitter to the line at the source where you have access to both ends of the line you are testing. I would suggest watching an online product video on the Pet Safe website to understand the nature of the product and its connection. Also read the manual, it is well written and informative. And pictures AND TEXT! My mower has a simpler broken wire connection system. The size of old matchboxes, you just tuck in the wire ends and clip them in place. Lasts a maximum of 5 seconds and you can easily bury it.
