The term 'Divining Tool' is a tool used to locate underground water sources. It is also known as dowsing or water witching. The most common divining tool is a ROD, which is a three-letter word. The ROD is usually made of metal or wood and is held in the hands of the user. The user then walks over an area of land, and when the ROD moves or points in a certain direction, it indicates the presence of underground water.
