Water divining, dowsing, or dousing is a tradition steeped in the lore of many cultures.
A forked stick, coathanger, or similar divining rod is used by a believer with the gift of dowsing.
It can be used to find an underground pool of water, a underground stream, or a leak according to believers.
The rod held rigidly and directly horizontal in front of the Dowser will jerk down violently at the present of water and often peeling bark.
A Dowser will use a normally use grid pattern and walk the surface to find the water.
Tradition says that minerals have also been found.
Here in Appalachia where I live, a peach twig is preferred.
How does water divining work?
