Seeing is believing
My husband, Ron, has the same kind of dowsing ability described in your profile of Vern Bandy (HCN, 11/22/10). His grandfather "witched" with a fork from a peach tree. Ron purchased a metal rod and has used it a number of times. He was project manager on the remodel of the senior center in Lake Havasu, Ariz. He used his ability to find pipes under concrete. The contractors were so impressed they wanted to buy the tool. Ron handed it to them, but no one could make it work! It works for Ron every time.
