My husband recorded this video about the tools and method he used to find the broken underground wiring for our Husqvarna Automower. We did a lot of moving our wiring around when our patio was built which messed up our initial boundary wiring. Unfortunately we knew we had a break SOMEWHERE, but not where. He was able to find the location, dig it up, and repair it using this tool.
Edit to add: The black wire on the transmitter is not attached to anything. The black wire on the receiver just hangs down to help you find the break.
