My wife and her grandfather could both dowse with branches, don't remember what type though but I bgelieve it was cherry. He found a spot with good pull at his new house and dug the well by hand. At 13' he hit good water. The well had ample flow until some deep wells were drilled in the area and it became less dependable. I climbed down on a ladder several times and cleaned it out to restore flow through the stone wall. My uncle used a pair of brazing rods to dowse.
