The term 'DOWSER's Tool' refers to a ROD, which is a three-letter word. Dowsing, also known as divining, is an ancient practice that involves using a tool such as a ROD or pendulum to locate underground water, minerals, or other hidden objects. The DOWSER holds the ROD in both hands and walks slowly over the area being searched. When the ROD moves or reacts in some way, it indicates the presence of the object being sought. Dowsing has been used for centuries and is still practiced today.
