Well, everyone’s suggestions were very good but everyone strayed from your question.......Diving in MIAMI. The top dive operator in Miami Beach is RJ Diving Ventures. They are on South Beach (Alton Rd. and 4 St.). Go to their web site and get info and diving schedule. Miami just got a new artificial reef, The Ophelia Brian on Dec. 30. You may also look into Neptune Memorial Site. Its a cementary. Its better than it sounds. Hope that helps. Ask for Mike or Georgia when calling RJ they will take great care of you.
