Well, I'm back, having used the Phoenix valve equipped DA Aquamaster on something like 20 dives at CCV. Lots of complimentary comments from fellow divers. CCV is a special place for divers, not for the jet-ski and tennis set, but for divers it sure has a lot going for it. Very friendly atmosphere, and relaxed diving. Kudos to the staff and management, our family had a great stay, and hope to return next year for another week at CCV.
