When I got certified in 1977 I bought what was the lastest trend in BCDs at that time. Although they were just called Bouancy compensators, they were a bp/w set up. It was viewed as a vast improvement of the mae-west BCDs that most of the older divers had. It's not really new technology, and you could start off diving this in your introduction to scuba class. The main differences is that many jacket type BCDs have a lot of bells and whistles built-in ( pockets & attachment points, etc.) while with a BP/W you need to add those. IMHO it is better to start diving with as simple a system and as few accessories as possible, then add things as you gain confidence and experience. I recently converted my AT-Pac to a BP/W type rig, and it has no d-rings, loops or attachment points on it. I will add those after a few more dives, one or two at a time, as I find out where I need them.
