I must have a knack for finding piping. Couple of years ago I went through a gaz pipe (twice - one up one down) mounting a wall bracket for a plasma on a wall. I wasn't drilling but I told my mate where I wanted it.
So if any of you guys need a stud finder, electrical or gaz line detector, water main, sewerage pipes etc... just drop me a line and don't listen to a word I tell you.
PS: I don't do petrol or gold. Only serious queries.
