Sixteen Inch Brass Dowsing Rods The instruments and tools dowsers use are simple. For the most part they are simply an extension of the human response giving clearer signals than can sometimes be detected without them. Angle Rods: These are L shaped rods, usually used in pairs. The shorter arm of the L is held in the closed palm with the long section parallel to the ground and to each other. Typically, when the target is reached the rods will cross indicating the spot. How to use: Hold one in each hand by the short part of the “L” so that the long part is parallel with the ground and so they can swing freely from side to side. To dowse is to search, with the aid of simple hand held tools or instruments, for that which is otherwise hidden from view or knowledge. It can be applied to searches for a great number of artefacts and entities. Dowsing is most commonly known by most people in association with searching for underground water; not surprising considering the absolute need for water by man and his animals and cultivated plants which sustain him.
