About Dowsing
The quick answer is that no one really knows - not even experienced dowsers. Some theorize there is a psychic connection established between the dowser and the sought object. All things, living and inanimate, the theory suggests, possess an energy force. The dowser, by concentrating on the hidden object, is somehow able to tune in to the energy force or "vibration" of the object which, in turn, forces the dowsing rod or stick to move. The dowsing tool may act as a kind of amplifier or antenna for tuning into the energy.
Skeptics, of course, say that dowsing doesn't work at all. Dowsers who seem to have a trackrecord for success, they contend, are either lucky or they have good instincts or trained knowledge for where water, minerals and the like can be found. For believer or skeptic, there's
no definitive proof either way.
Case histories and demonstrations of dowsers may seem convincing, but when dowsing is exposed to scientific examination, it presents a very different picture. The natural explanation of "successful" water dowsing is that in many areas underground water is so prevalent close to the land surface that it would be hard to drill a well and not find water. In a region of adequate rainfall and favorable geology, it is difficult not to drill and find water!
Some water exists under the Earth's surface almost everywhere. This explains why many dowsers appear to be successful. Tolocate groundwater accurately, however, as to depth, quantity, and quality, a number of techniques must be used . Hydrologic, geologic, and geophysical knowledge is needed to determine the depths and extent of the different water-bearing strata and the quantity and quality of water found in each . The area must be thoroughly tested and studied to determine these facts.
1)
Find a forked ("Y"-shaped) branch from a tree or bush. Hold the two ends on the forkedside, one in each hand. You may want to experiment with holding it with your palms facing up or down; one may be more effective than the other. Hazel or willow branches were commonly used because they were light and porous, and were believed to better absorb vapors rising from buried metals or water, thus weighing down the un-forked end
and pointing towards the source.
2) 
Bend two identical pieces of wire into an "L" shape and hold one in each hand by theshort part of the "L" so that the long part is parallel with the ground and so they can swing freely from side to side. You can use coat hangers to make these rods. Some dowsers claim certain metals, such as brass, to be more effective.
