Wayne contacted us a few days ago to say that his wife Rosie had lost her wedding ring while gardening. She’d been pulling weeds, amending the soil, and planting new plants when she discovered the ring was missing. This was strange, because the ring fit snugly on her finger, and had never come off before. They had tried using a metal detector, but couldn’t find the ring anywhere.
When we arrived, Rosie showed us the front garden plot. It wasn’t large, perhaps 30 feet by 2 feet. We were concerned about whether our larger metal detectors would work, because there were railroad ties forming the front border of the plot, and a wall along the back side, and both contained screws and other embedded iron fasteners.
So we started by scanning the plot quickly with a handheld metal detector called a pinpointer. We found about a dozen nails and sprinkler parts, but no ring. Now we knew the top layer of soil was mostly clear of metal, but we still had the screws along the front and back to contend with.
We scanned the bed again with a larger metal detector set to discriminate out, or ignore, most iron. This is a tricky process, because if you tell the detector to discriminate out too much iron, you will lose the ability to find smaller gold targets like rings. But we had to be able to ignore those pesky screws.
It worked. About 5-6 inches deep in the soil, buried under one of the new plants, we found the ring. It’s a beauty, inset with black diamonds, one of the most unique rings we’ve recovered. Rosie was very happy to get it back.
