you did not take the speciality course..you did an adventure dive..the dry dive is an elective dive on the advance course..you only get the adv ow card..the 5 dives should have bee the core dives-navigation,deep and three electives,one of which you choose as dry suit dive..the dry suit speciality course is much more involved..c555:I got drysuit trained as part of the advanced course. It was just one of the five specialty sections. It only cost about $100 more for the rental, pool time, and 5 dives with an instructor. I didn't get a card or any other proof but so far i haven't needed it.
