Dowsing is a skill that can be learnt by anyone who has the patience, develops their awareness, and acquires a basic knowledge of its principles and mechanics. It is used for instance in water-divining, in medical dowsing, archaeology, for map-dowsing, and for time-dowsing, probably among others. It is a mental 'tool' that can be used for analysis through intuition and therefore fits between scientific analytical logic and imagination, intuition and subjective meaning. It is always used with a physical tool of some sort to amplify the signal - hazel twigs, metal rods, pendulum are the commonest ones.
