How do I find a pet containment wire that was buried around my property 5 years ago.? - pet containment system wiring patterns

The copper wire buried around the property of a system Confinement dog. I have not been used for several years and now want a new system, but need to know where the old cable. I know the approximate location, but we need to know precisely the opposite would occur long before the search. Do you know of a way to go and that the property can determine whether the cable is it? Is there any kind of detection device?
