All things give off energetic radiation. Our own senses can feel and
measure these energies. The pendulum becomes our communication device
between consious and subconsious. A pendulum receives information from
the vibrations and energy waves emitted by people, places, thoughts
and things, and has been used for centuries.

The practic of dowsing, either by pendulum or rod, is even noted before
the time of Queen Cleopatra, who's own advisors used them extensively.
