Lost Ring during wasp attack, returned with a Metal Detector

Thomas got out of his cab at the Kelowna hotel, only to be swarmed by wasps. In the process of waving his hands at them he lost his wedding ring, a group of people searched for it in the grass, to no avail. He called me and I responded within 15 minutes, he showed me the location by the tree with the wasps. I did a grid of the grass that was full of old construction metal. Being on the surface the ring was a good target, and within 10 minutes the ring was back on his finger. The ring belonged to his father, and he had it resized for his own wedding, it was very sentimental to him.
