“It is what it is - a 1litre steel cylinder painted white with a vertical valve. It is not bulky and has sufficient volume for dives to 80-100m, unless the suit is is used as the primary buoyancy control or the dive has a saw tooth profile. In which case you may need a larger capacity. My suit is inflated to being just comfortable and any additional lift is provided by the wing.
Unfortunately the cylinder cannot be purchased without a valve. This option would reduce the price as the valve is not always wanted.
Aquanauts offer a competitive price and fast delivery. I will continue using them for future purchases.”
