<font color=blue>I know that some on TBN totally discount dowsing as folly</font color=blue>
And I wouldn't hold that against them, either. /w3tcompact/icons/laugh.gif
Fact is, Dave, that I, like my dad before me, prefer solid science to smoke and mirrors. Dowsing, however, is one of those fringe phenomenons that have intrigued scientists and engineers for many years. I think you already hit the nail on the head when you said, "<font color=blue>The dowser is doing the doing</font color=blue>". The stick, rods or whatever, are just sort of amplifiers that indicate any minute reactions the dowser is having to his environment.
My own personal experience with dowsing came from an encounter with an EBMUD (East Bay Municipal Utility District) engineer. He was called in by a city work crew to locate some underground pipes in my neighborhood. When I see stuff like that going on, I naturally wander out and become a part of it. /w3tcompact/icons/grin.gif Fortunately this guy was the friendly type and he was glad to explain his procedure to me.
This "engineer" used dowsing rods -- two welding (brazing?) rods bent into an 'L' shape. He held one in each hand, sort of like pointing pistols, only held very loosely so they were free to swivel left and right. He starts off by letting them settle into pointing straight ahead, so the two rods were parallel. He then proceeded to walk the target area slowly with the rods still pointing ahead. Eventually the rods started to swivel towards each other. At a certain point, they abruptly crossed straight across each other, forming an 'X'. That meant they were directly over water.
I thought sure he was pulling my leg (standard joke for annoying onlookers?), but after using this method to triangulate an exact spot, the crew started digging and, sure enough, they hit the pipe dead on.
Not satisfied that I wasn't still being played for a fool, I invited the water guy to walk by my front yard on his way back to his truck. As a good-humored challenge, I asked him if he could locate the PVC sprinkler pipes under my lawn. This was to be
my little joke, 'cuz although the sprinkler heads were fairly obvious, I had laid the pipes in an unusual and certainly unconventional configuration (too long a story for this thread).
As you might have guessed, it took him a matter of minutes to trace several of the pipes
exactly. He started to ask me why on earth I used that pattern, but I cut him off and said, "teach me how to do that!"
He walked me through it, and I even located some of my pipes, but since I knew where they were, I was pretty sure I was just subconsciously manipulating the rods myself. He left the rods with me when he left, so I wandered the neighborhood with them and never found a darned thing. /w3tcompact/icons/blush.gif
So as far as I'm concerned, dowsing is an unsolved mystery. I can't explain how that guy, or the old fella that years later found my dad's spring did what they did. The fact that I can't explain it with known scientific principles only reminds me that there is a whole
lot of stuff I don't understand.
