What does dowser mean?
A dowser is a person who claims to detect hidden things beneath the ground — most often water, but also minerals, pipes, or lost objects — by means of a divining rod, typically a forked twig of hazel or willow, or sometimes a pendulum. The practice, known as dowsing or water witching, has deep roots in European folk tradition and remains in occasional use by farmers and well-drillers, though controlled scientific tests have repeatedly failed to show that dowsers perform better than chance. The word can also refer, less commonly, to the rod itself. A dowser is said to react to subtle movements of the instrument as it passes over the sought substance. Because of its association with folklore and the paranormal, calling someone a dowser usually signals traditional or rural practice rather than formal science, and the term frequently appears in writing about skepticism, history, and countryside custom.
A person who uses a divining rod, pendulum, or similar device to search for underground water, minerals, or lost objects.
"A local dowser was brought in to help choose the site for the new well."
This is the standard and dominant sense.
A divining rod or other instrument used in dowsing.
"He gripped his dowser firmly as he crossed the field."
Much less common than the agent sense; most writers prefer 'divining rod' or 'dowsing rod' for the instrument.
Regular plural; applies to both the agent sense and, rarely, the instrument sense.
"Dowsers from across the region gathered at the annual well-dressing festival."
Dowsers have been finding (or failing to find) water with forked sticks since at least the 1500s — and controlled tests have yet to show they beat chance.

Etymology of dowser
The noun 'dowser' derives from the verb 'douse', whose own origin is uncertain; it first appeared in English around the early 17th century, initially meaning to plunge into water or extinguish, before coming to describe the practice of searching for water with a rod. The connection between the verb and the divining sense may lie in the notion of dipping or plunging toward water. The word is essentially English-specific, with no widely recognized direct cognates in other languages, where parallel terms such as French 'sourcier' developed independently.
How dowser is actually used
The word carries a slightly folkloric, rustic connotation and appears often in discussions of folklore, rural tradition, and skepticism about pseudoscience. The agent sense ('one who dowses') is dominant today; the instrument sense is rare. In American folk usage, 'water witch' is a common synonym, though it can read as informal or regional.
