When I grab a set of my rods, pass them over a waterline, and theynimmediately cross, forming the "X", and it does that every time, I think that validates the effectiveness of the tool. Oh, and btw, I have never dug a well, but I have certainly drunk from several. Have a nice day.
That explains it. You know there is water there, and you believe the rods will therefore cross, so you unconsciously move them.
From Wikipedia: "Science writers such as William Benjamin Carpenter (1877), Millais Culpin (1920) and Martin Gardner (1957) considered the movement of dowsing rods to be the result of unconscious muscular action.[59][60][61] This view is widely accepted amongst the scientific community.[8][9][62][63] The dowsing apparatus is known to amplify slight movements of the hands caused by a phenomenon known as the ideomotor effect: people's subconscious minds may influence their bodies without consciously deciding to take action. This would make the dowsing rod susceptible to the diviner's subconscious knowledge or perception; but also to confirmation bias.
That's why science operates as it does. If your rods crossed someplace you didn't know there was water, and it turned out there was water there, that would be evidence. That's why I asked about wells. If you were successful in finding water for a well someplace where people had trouble finding water, that could be evidence. It still wouldn't be a proper controlled science experiment though.
