L-Rods[ edit ] Two L-shaped metal wire rods Water dowsing dowsers today use a pair of simple L-shaped metal rods. In the philosopher John Locke, who was born in the West Country, used the term deusing-rod for the old Latin name virgula divina.
Ongley tested 75 dowsers' ability to detect water. This type of fallacious reasoning is known as post hoc reasoning and is a very common basis for belief in paranormal powers. Water was pumped through a pipe on the ground floor of a two-storey barn.
Before each test, the pipe was moved in a direction perpendicular to the water flow. In any case, the hypothesis was not tested and I am not sure how one would go about testing such a claim.
Various theories have been given as to what causes the rods to move: It is essentially unscientific and invalid.
On the upper floor, each dowser was asked to determine the position of the pipe. We carefully considered the statistics of these correlations, and they far exceeded lucky guesses.
When dowsers are scientifically tested and fail, they generally react with genuine surprise. Dowsers, he thinks, somehow sense these gradients in a hypersensitive state. The Mexicans think the rod can detect drugs. The term 'radiesthesia' certainly sounds more dignified and scientific than 'dowsing.
A French priest and dowser, Alex Boulycoined the term radiesthesia in and founded The Society of Friends of Radiesthesia. When something is "found", the rods cross over one another.
Hazel twigs in Europe and witch-hazel in the United States are traditionally commonly chosen, as are branches from willow or peach trees.
Denis Briggs carried out dowsing experiments at the grounds of various churches. The dowser then went over the same area after the scientific team had made their choices and he picked 7 sites to drill.
L-Rods[ edit ] Two L-shaped metal wire rods Many dowsers today use a pair of simple L-shaped metal rods.
Bouly apparently believed he and others had a special ability to sense emanations of some sort being released from underground water, buried bombs, and vibrations from microbes in test tubes. He believed the experiments provided "the most convincing disproof imaginable that dowsers can do what they claim",  stating that the data analysis was "special, unconventional and customized".
Glass or plastic rods have also been accepted. None of them was more reliable than chance. If the object is long and straight, such as a water pipe, the rods may point in opposite directions, showing its orientation. To make their point that dowsing is a sham each has staged demonstrations in which dowsers were asked to find buried pipes.
Dowsers did no better than the laws of chance predict.
Dowsing is an unexplained process in which people use a forked twig or wire to find missing and hidden objects. Dowsing, also known as divining and doodlebugging, is often used to search for water. One of the longest-running of these disagreements centers on dowsing, a supposed sixth sense that enables people to find underground water using a forked branch, pendulum or pair of bent wires.

"Water dowsing" refers in general to the practice of using a forked stick, rod, pendulum, or similar device to locate underground water, minerals, or other hidden or lost substances,and hasbeena subject of discussion and controversy for.
Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, gravesites, and many other objects and materials without the use of scientific apparatus.Water dowsing
