At a house we owned where the well had run dry, we hired the guy who ran the local water treatment plant to come and dig us a new well. Sure enough, came out, dowsed, and duly a backhoe dug down about 10 foot, and we had our new well.

This is in N.E. Scotland, back in about 1991. The funny thing was that my dad was a total skeptic on this, and such other 'discredited' things as spoon-bending, and even he had to admit the guy had some not easily explainable talent.
