I don't have a GPS for it. You could probably call Hall's and ask them for the GPS for it and they may give it to you. You're right though, it is a wonderful dive especially for a camera. There are so many thousands of fish there it's amazing. I had always wanted to dive with sharks and the last day of my time in Marathon I went to Sombrero Reef and saw my first nurse shark..about 6 feet long. Then we sped over to the barge wreck and I saw my second nurse shark...about 4 feet long. This second nurse swam around us with no fear, between my legs and around me all over..it was quite cool. I loved it. You can also swim in and out of the remains of the wreck. If you look close, on one of the ends of the wreck, not sure which one, there is a small passage that you can just fit through. There is no access to the surface once you get in it so it's considered an overhead penetration but it is amazing. I went through and barely had enough room to look behind me and saw the nurse shark following me through. The grouper there had to be twice as big as me, it was huge. An amazing dive no doubt!
