I dove with Cayman Turtle Divers for 2 years and have nothing but praise for the whole operation. Look them up on Trip Advisor. Great reviews. They come off the public dock at the north end of SMB or the Yacht Club on the other side depending on conditions. I believe they will pick you up anywhere reasonably close. Very accommodating and very pleasant to be with. For most of the dives I went on there we just myself and my girl friend and 2 guys from CTD.
