I have a general idea where all the runs are buried but not to the exact inch. I can just start digging  lightly to find the PVC but that's a long process. Is it possible to use a metal detector? Something like the beachcomers use.The PVC is about 4''-6''  below the surface. Frost line is not a problem in the Tn delta.  Has anyone used one to find coax?

Most rental yards have a cable locator.  It comes with a little box with 
a cliplead that puts a low frequency AC on the cable (or pipe) you're 
trying to find, and the locator that looks for the signal.  Used all the 
time with modern plastic gas pipes (typically with a wire wrapped around 
it to facilitate this process)
