In my quest to find out if water witching really works, I came across Norman Fitzgerald, LS, the senior survey technician for Fairfax County Water Authority. Norm is a believer in water witching "because it works," he says. He demonstrated his divining technique for me in the parking lot outside his building.
There are several methods for performing dowsing: the use of a "Y" shaped branch, two "L" shaped wires or a pendulum. I photographed Norm's technique using "L" shaped wires to create this illustrated how-to guide.
