When the power company wants to follow the path of a buried cable, they
attach a gadget to one end and walk along the ground with another
gadget. Looks real easy when you have that $7000 pair of gadgets.=20

Any idea what inexpensive thing I could modify to get a similar effect?
I don't need to do it on a live wire, and the maximum depth underground
is one meter or less.

Thanks,
Bob
