rhabdomancy

Since the Middle Ages dowsing applications have been employed in alternative traditions including ghost hunting, raising spirits, mediumship, divining, fortunetelling and detecting ley-lines - perceived telluric energy lines between distant objects or locations. Dowsers claim that they can find missing and hidden objects and minerals like jewelry, treasure, persons, buried pipes, oil deposits, bones, water and even archaeological ruins. In Colombia, South America, rod dowsers are not uncommon and their services have been employed for several millennia.
