Once you begin to look at pendulums for dowsing you may become overwhelmed with the number of choices. The most important thing to remember is that you are the real instrument, not the pendulum, for the intuitive information to come through. The power is in you. My rule of thumb is to pick the pendulum that you think is attractive. Don’t worry about the length of the chain, the size, shape or color of the weighted object. Anything that swings works. Really.
