The video demonstrates how to find a break in your boundary or perimeter wire using a wire locator tool.

 Jason from Robot Lawn mowers shows how to use the NF 826 Wire Break Locator by showing an installation route that has a break in the perimeter wire. Jason disconnects both ends of the wire and pulls them out. He connects the red lead of the transmitter to one of the leads and connects the negative lead to the screwdriver pushed into the ground.

 Then he turns on the transmitter and sets the signal strength to one. The receiver is also turned on, and the signal strength is set to Auto. When he gets close to the wire, the receiver beeps, and as he moves further away, the beeping stops.

It is advised against setting the signal strength too high, as this can pick up signals from much further away. Instead, a setting of one or two at most is ideal. Following these steps, it is possible to locate the break in the wire and make necessary repairs.
