We are on an island, and bought a petsafe one and installed it ourselves. We bought a large spool of heavier duty wire, and basically other than the paths we use (where we buried it) we laid it down and let the leaves etc cover it up. It goes out past the dock - it is deep where it is, and doesn't seem to bother the dogs any when we pull up.
Our only issue, since we did not bury it, is it has gotten blasted by lightening!
