I can relate an interesting experience from a 2009 trip to Arizona using bronze L-rods (without handles). Met prospectors who were there because CA dredging ban was taking place. One of them once had a mining claim Quartzsite area. We tried finding it but each small peak seemed like the next. Found his old claim, only after following my dowsing rods.
My dad also uses those type rods. We have easily located quartz veins using the Electro-scope. It’s an expensive gimmick. Only in that it is simply a dowsing rod. No need for any of the electronics inside it. works like a dowsing rod only it’s directional.
I had read early treasure magazine articles about the Electro-scope. Europe once had a competition with several buried safes full of silver.
It was popular in the 1980’s thru the 1990’s. I can say there is a dowsing affect, but it’s difficult to use effectively due to the number of things that it is attracted to. It liked something in the ground (minerals or water?), non-ferrous and ferrous targets. You could pick up a cast iron stove from hundreds of yards away. Dad found a silver dime, a pocket knife, chewing gum wrapper, brass cartridge case, quartz vein, ect. But no treasure.
