[cool][#0000ff]Make sure that she knows the difference between an inflatable PFD and a buoyancy compensator vest (for diving). The latter is designed to provide additional weight to offset the bouyancy of neoprene wetsuits and other diving gear, to help the diver get down better.[/#0000ff]

Divers wear lead to overcome their own positive buoyancy and that of their wet suit. The BC vest provides variable, positive buoyancy to compensate for the negative buoyancy of the lead. And since the buoyancy of neoprene varies with depth, neutral buoyancy changes as the diver's depth changes.
Not to mention you have to go to a dive shop to buy a BC.
