Dowsing is an ancient practice whose origins are lost in long-forgotten history. It's an ancient art used for finding water, buried treasure and even missing people. Usually, this is accomplished with the aid of a dowsing stick, rods or a pendulum. Dowsing is also known as divining, water witching, doodle-bugging and other names.
This may have been mentioned in the Bible, although not by name, when Moses and Aaron used a "rod" to locate water. The first unambiguous written accounts of dowsing come from the Middle Ages when dowsers in Europe used it to help find coal deposits.
