Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, gravesites, malign 'earth vibrations' and many other objects and materials without the use of a scientific apparatus. Dowsing is also known as divining (especially in reference to interpretation of results), doodlebugging (particularly in the United States, in searching for petroleum) or (when searching specifically for water) water finding, water witching (in the United States) or water dowsing. Dowsing remains popular among believers in Forteana or radiesthesia.
