I am planning a Caribbean trip for March of '09. I would like to get in a couple days of tech diving to 200 fsw, along with some recreational dives with my wife. Can anyone offer suggestions on places where I can accomplish this? Looks like DiveTech on Grand Cayman is an option, and maybe Cozumel as well? Any suggestions on dive ops or locations where I could do some rec and some tech would be greatly appreciated.
