Not sure if it's been claimed but last year in LJ martin bizal was diving with us when he dropped a fin. When he reached for it he dislocated his shoulder. That was an eventful trip. I'll ping him and see if he lurks here.
Check your pm when you get the chance. Thinking it’s my buddies. Would be awesome to see the look on his face if it’s his fin. He dropped them both off the swim step lobster diving. Another friend of his dove the area and found one of the fins.
