Inflator's are the key to BCD's...
I disagree: fit is first.
BCD Jackets give inflation of the air cell around your body and unser your arms. They tend to keep you up-right on the surface when you are relaxed. Back Inflators or Wings give you no floatation in the front. They tend to make you go face down on the surface when you are relaxed. Both types (Jacket or Back Inflators including wings) are widely used in diving. Back Inflators will keep you up higher in the water when inflated. You need to learn how to use them if you have only been using a jacket. Once you have tried them you can dive them in openwater with ease and comfort, but if you have not used one yet, then try in pool first.
I disagree in part. If you have properly adjusted your trim, a back inflate will not make you go face down. Also, I find a jacket keeps me up higher out of the water but I consider that niether here nor there.
More than anything else, the right backplate (some brands offer sizes) and a hog harness will fit anybody. Big shoulders, tiny waist. The reverse. Tiny waist and tiny shoulders. Huge waist and large shoulders. And it will hold your tank rock steady. If the straps are adjusted well (and you use the crotch strap), the whole unit will be rock solid.
