I've wanted to learn more about this technique, I've only been able to acquire information on the subject of dowsing rods, and a bit on Pendulums, but I have yet to get one so they are quite useless.
Hey Sandsted....A Pendulum can be anything that will swing from a string. I have read of water being located with coat hangers and brass rods. The only guy I know prefers to use a branch from the location he is dowsing...Art
If I wanted to use a screw I would go to a craft store and get a small eyelet or ring. I would then glue it in the screw driver slot. If that doesn't hold it use J B Weld...Art
he has a really nice dowsing pendulum, which has certain empowered runes to enhance it's dowsing ability or something. I love using runes for casting and I like dowsing, so combining them sounds like a genius idea.
