I just very seldom need to trace wires. A couple of times I could have used one, but not often. If I find I need one I will buy it. I just don't think it is a piece of equipment you need to get started. Once the wires are underground they don't get broken often. When they do it is when someone is digging and they know where it is cut. Like I said I would buy one in a heart beat if I found I needed it.
