German physicists concluded from their massive experimental study that water dowsers unquestionably have a remarkable, mysterious skill. Those results, however, provide the most convincing disproof imaginable that dowsers can do what they claim.
Below is a figure from the article that shows there is no correlation between the location of a water pipe and the prediction by the dowsers. Other figures show that simply guessing the mid point of the field would provide better results than the efforts of the Dowsers.
