Here is where you make your choices about the tools you use for your dowsing.
Most beginners choose L-rods and pendulums for their introductory work.
The typical dowser will find these quite satisfactory. The notion is that you take a sample of that which you are trying to locate and place it in the dowsing tool. Others maintain that the key to successful divination is keeping a clear idea of your search target within your mind as you quest for the goal. The aurameter has some of the features of an L-rod and some of the features of a bobber. Dowsers differ in their beliefs concerning the efficacy of the various devices.
