The "Pendulum Books" by Frank Glahn are probably the most comprehensive work on pendulum dowsing ever created. There seems to be no aspect that he does not explore in his six-volume series. He truly motivates everyone to learn pendulum dowsing and illustrates all the essential fundamentals and advanced techniques. Frank Glahn himself was so successful with the pendulum that he was even called upon and recognized in criminal matters before the oath and district court. Glahn dowsed nearly everything concerning his personal life. This is reflected in his extensive and unparalleled wealth of experience, which he conveys in an accessible and straightforward manner—making it understandable for everyone—in his books. Each volume covers a particularly special area in detail, and numerous illustrations facilitate comprehension. From metal, mineral, and plant to body, soul, and spiritual dowsing, the reader receives an exceptionally thorough pendulum education that enables them to conduct all conceivable pendulum experiments themselves.
