Andrew lost his ring in Lake Michigan while swimming at a 4th of July picnic. He discovered Ring Finders a few days later and arranged for a hunt. I traveled with Brian Pasterski, fellow detectorist, because he is a good detectorist and seasoned diver if we need to go deep. Luckily, we only had to search in neck-deep water, which is very refreshing on a hot, sunny day. We used Garrett AT Pros. There were large limestone rocks, which could have been bad if the ring slipped between some large ones. Luckily, Brian detected it under a small rock and dove down to retrieve it. There was no junk in the rocks which made it much easier. The only signals we found were the ring, and one high signal buried deep. Andrew was overjoyed to have it returned.
