The AP SMBCi – self-sealing SMB with inflation cylinder has all the features and advantages of the AP SMBC together with an independent inflation mini-cylinder (0.1 litre 232 bar available with either DIN or Int A-clamp fittings). This not only makes deployment a very simple procedure but it allows you to conserve expensive mixed gases for what they are intended rather than SMB inflation. The mini-cylinder is easily replenished by decanting from a standard air cylinder. It folds neatly away inside the rolled-up SMB and the SMBCi can then be stowed in a pocket, attached to an external D ring.
