TCDiver1:Not in my neck of the woods.
Not in most places i vacation dive.
So i would say no.
Actually, I live and dive in your neck of the woods and it seems to me that I have noticed more people wearing BP/W set ups this year than last year. I do consider myself a recreational diver, however I dive as many shipwrecks as possible. It is on these charters that I have seen more BP/W set ups. I have also noticed that my new LDS, the original one did not like my gear configuration, is starting to stock and actively promote a BP/W set up. There are other dive shops in the area are doing the same. I have also discussed this gear set up with other divers, because of there interest in wanting to make a change.
So I would say yes there has been an increase.
