Dowsing is also known as "Witching". I am not sure about the Metal rod dowsing, but scientistsdo say there is a scientific reason why dowsing with a split willow wood twig works. It has to do with increased humidity escaping above where the underground water is. Sinvce people are reporting Metal dowsing also works, I wonder how and why. Jeffery G.
