I discovered that my pendant necklace..works for me to dowse with too :)
My fingers get tired when I have questions come to mind while I'm driving, and do the finger dowsing. So I took my pendant off and used it instead. It works as long as the road is straight and smooth.
so, on the way to town, I also started wondering about warts being man made, and I also got yes. Blows the wives' tale of warts coming from frogs..or maybe that was their original source-- my husband tells me I think too much. It's fun, sometimes maddening, to be able to "don't wonder, dowse for the answer".
