If you don't have any dowsing rods you can just uncoil & bend a couple of coat hangers into a "L" shape. Hold the short part of L very loosely with each hand between your thumb & index finger so that the long part is straight out ahead of you. Again, hold the short ends very loosely so the rod can move on its own.

I once dowsed an artesian well for my husband on a ranch we lived on in Yosemite area using just coat hangers. We already had a well at the main house but he wanted one for the second house he was building. He used it for the 2nd home but also used it to feed 2 ponds he developed. You just need to find the point where the underground rivers come together. After that I dowsed for wells for a couple of our friends & was successful but don't like to do it for other people because if I should ever mess up and pick a wrong spot the drilling is expensive! There are a lot of professionals out there that do it for people.

Haha, maybe a couple of coat hangers are good items for the BOB - to find water.

Also, it's not just water that you can dowse for.

So go get a couple of coat hangers and give it a try even inside your house. It's fun and you'll find out where all your water pipes are under your house.
