I am working on an idea to explain dowsing. I doubt that it is right in that there are many others more knowledgeable and better equipped than I who have failed to discover a mechanism.
I am pretty certain that the rods move as a result of micro movements in my wrists. This does not explain why they move under specific circumstances.
I am certain that the effect is biological rather than mystical.
If I hold the rods in front of me I can get them to cross and uncross by thinking.
I do not think of this a telepathy in any form.
I once dowsed the local church yard as the sun was setting and as the sun flashed between each big grave marker the rods swung.
At Tredegar House, Newport, I discovered a straight line running across the front lawn. The property manager was unimpressed, saying that it was just a private water main put in by the penultimate Lord Tredegar. I had no idea that such a pipe existed.
If I immobilise my elbows by holding them tight to my body then the rods don’t move in any predictable way.
I dowsed my garden shortly after we arrived here nearly fifty tears ago. I got a very wobbly but definitely linear result. The line ran diagonally across a very rough patch. While I was staring at the ground my wife was laughing out loud. She called out to look UP! The power line to the village hall next door followed the line that the rods indicated.
I am only interested in physical dowsing rather than any predictive or remote use of the activity.
