Answer

metal detecor is more than enough for finding the
underground cable . i have used when i work in qatar . when
we have to digg for cable laying or for any other purpose
we have to search there whether is there any live cables or
cables underground . exactly not remember but upto some
length of depth we can found underground cables . with out
metal there is no cable ..... so metal detector is morethan
enough .
