Dowse Pendulum

A dowsing pendulum is typically a rock or crystal that hangs on the end of a string or chain. The pendulum is used as a way
of gaining spiritual and material insight. The dowsing pendulum works by tapping into your subconscious mind.  When you ask a question, your subconscious mind responds by influencing the nerve endings in your fingers causing the pendulum to swing in response. In other words, your body outwardly expresses your inner knowing.
