Tomislav Jeremić water divining (Radiestesia) in Dražanj 01.September 1993Language is Serbian, but video shows whole process of water divining in field for drilling wells.Text below from  ----https://www.crystalinks.com/dowsing.htmlDowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, gravesites, and many other objects and materials without the use of scientific apparatus. Dowsing is considered a pseudoscience, and there is no scientific evidence that it is any more effective than random chance.Equipment includes rods, pendulums, police and military devices.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. A Y- or L-shaped twig or rod, called a dowsing rod, divining rod (Latin: virgula divina or baculus divinatorius), a "vining rod" or witching rod is sometimes used during dowsing, although some dowsers use other equipment or no equipment at all.A dowser is sometimes called a "Water Witch"The testimonials of dowsers and those who observe them provide the main evidence for dowsing. The evidence is simple: dowsers find what they are dowsing for and they do this many times. Scientific thinking includes being constantly vigilant against self-deception and being careful not to rely upon insight or intuition in place of rigorous and precise empirical testing of theoretical and causal claims. Controlled study of dowsers, has shown that dowsers believe in what they do - but much of it is by chance.Scientists have tried to understand the physical basis of dowsing; what factors link the movement of the rod in the dowser's hand to underground structures. No one has yet successfully explained the dowsing signal and for now it remains by chance - or another psychic tool sometimes used for balancing and healing one's electromagnetic energy field.
