After 20 years of not diving I am going to Playacar. The resort gives
certified divers a one tank dive each day. I checked into a refresher course
and all they do is go over the dive tables. Since I am not going to do any
repetitive dives do I need the refresher? Should I do the whole course
again? Or review my manuals and go on the dive when I get there? I am sure
things have changed, new equipment, etc. Any comments would be appreciated.
