We were cleaning up dependants beach, and the person that found the largest piece of trash won a special trophy. Me and another diver had scoped out the beach in advance and found a large wood structure on the bottom, so we decided the only way to raise it was to take a deflated life raft down and attach it to the object than inflate it and raise it to the surface, and that worked so we got the trophy for the largest piece of trash found.
