Types of Dowsing
Forked stick. The most traditional method uses a small Y-shaped tree branch (most often from a willow). The dowser holds the branch parallel to the ground by the top of the Y shape, then walks over the area to be probed. When the dowser passes over the sought object, the end of the branch is drawn down, pointing to the spot at which the object can be found.
Rods. An alternate method uses two L-shaped metal rods, one held in each hand parallel to the ground and parallel to each other. In this case, when the dowser passes over the sought object, the rods either swing apart or cross each other. You can easily make dowsing rods from wire coat hangers.
Map Dowsing. Some dowsers don't even have to visit the location to be dowsed. For them, a map of the area is sufficient over which they hold pendulum. They know they have located the target area when the pendulum begins to move in a circle or back and forth.
