How to Find a Broken Underground Wire for Husqvarna Automower

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.

So let me get this straight, I can use a multimeter and hook it up to a radio, and put one multimeter stick in the ground and the other on the antenna and if the one on the ground makes a sound the radio antenna while it's on will show higher volts?

Would u recommend the pro for deeper lines..say 2 ft?

Are we allowed to use handheld FM am radios to detect ground wire via multimeter ?

My transmitter is in my garage and I think it’s too far but there’s nowhere else my pet fence is. The main box is in the garage so what do I do

Dude - can you answer the question where did you connect the black wire? Did you connect to to an earth?
