I'm not sure if that's the correct terminoligy to describe the two main types of BCD's. The two that I'm talking about are the one's that inflate totally around you compared to the ones's that just inflate on your back (you don't feel it sqeeze your body). First of all what is the correct terminoligy for these two BCD's? Second, what are the advantages and disadvantages between the two? Just got OW certified and already have a dive computer, mask, and fins. Just trying to find some information on BCD's because I believe that's the next logical step of equipment to get.
