He claimed to be able to locate nothing but water with his dowsing rod.1996, Richard Webster, Dowsing for Beginners: The Art of Discovering Water, Treasure, Gold, Oil, Artifacts, Llewellyn Worldwide, →ISBN
   • The instrument a dowser uses is called a dowsing rod, dowsing stick, doodlebug (when used to locate oil), or divining rod.
