I'd never have imagined that water dowsers would have a website, let alone an association and a website for it. http://www.dowsers.org/ I've only seen it attempted twice, at a golf course where 2 greenskeepers believed in it, and the other 5 didn't. One guy trying it had said it always worked, but in a demonstration where I was present, said he could figure out why it does not seem to work when I'm around. And it was a failed demonstration with about 8 people watching. Anyway, these folks are out there, and apparently have slightly infiltrated the garden and landscape green industry.
