Last week at a reception at the Computer History Museum in Mountain View, my friends Kathryn and Kevin told me that he had lost his wedding ring while coaching their daughter’s soccer team the week before. Their wedding anniversary was fast approaching. Obviously we had to do something about the lost ring!
We met at the soccer field in Menlo Park on Saturday afternoon. The team had practiced across a very large area, and unfortunately Kevin did not notice when the ring left his finger. But he did suspect that it may have happened when he was kicking balls to the girls from one end of the field. So we set up a search grid in that area and I got to work with my metal detector.
The grass was thick and well-watered, which was both good and bad news. Good news in that the grass may have hidden the ring from passers-by, but bad news in that we found several coins buried in wet, muddy patches. If the ring had fallen into this mud, it could already have been pushed an inch or more beneath the surface. Normally for a ring that was recently lost, we don’t dig into the dirt for targets, but in this case we did dig whenever we encountered a target in mud.
After about 45 minutes, I got a solid tone in the right range. It was shallow, but when I spread the grass apart, we couldn’t see anything. After poking under the grass roots for 10 or 15 seconds, Kevin’s platinum and gold wedding ring popped out. It hadn’t been buried, but it was absolutely invisible under the grass.
Oh, did I mention that we found the ring on Kathryn & Kevin’s wedding anniversary? Everybody went away happy!
