Kray, dowsing is just good ol' fashioned pretend. There are folks who want to be successful Big Time Treasure Hunters so they wrap themselves up in a world of pretend, like dowsing, or auras, or treasure markers, or KGC vaults. It's fun and pretty harmless, mostly just a waste of time & money. But, hey, it's their time & money. Dowsers like to pretend they're not pretending, but at least on a subconscious level they know they are. That's why they shun any kind of scientific inquiry, they already know what the outcome will be.
