What a great forum! After years of diving snorkeless I found myself diving a wreck in Queensland (and found out its actually law to dive with one here) There was a big surface chop and we had to wait at desent line for other divers.With no snorkel I had to either suck on reg and use valuable air or struggle not to inhale waves! This experence plus a couple off opportunities To snorkel with unexpected guests. bettween dives has made me change my mind.Go snorkellers!
