Hard Shell Buoyancy Compensation Devices on E-Bay

[SeaRat]

There are currently two hard shell BCD's on E-Bay. One I already have. It is the White Stage BCD Hard Shell:


This is what the White Stag hard shell BCD looks like.

The other is one I have never seen before. It looks like there are three of these available:

This one doesn't look right, as I don't see any way of introducing air, and don't see how it could work.

This one looks interesting, but again I don't see how air is introduced into the design:

I told Diver Don about those auctions. Not sure if he saw them.

I did look at these but at this point I feel have enough systems that are similar to these that are working (or darn close) so I'm passing on any additional units. Perhaps someone with room left in their house for additional Scuba gear can pick one or two of these up.
