These are copper coated rods (5X13) with a copper handle. There is a double sided instruction sheet on how to use them.
A form of dowsing rods are the pair of L-Rods (also called
angle-rods). Two rods are used,
one in each hand. The small branch of the L is held lightly in the hand, the longer stems facing
forwards in parallel. As the dowser approaches the target the rods will begin to turn
towards each other and
possibly even cross. If both rods turn the same way then this can be a direction
indicator.
