How we calculate scores →About this gear
S50 provides 50 cu ft of air in a 7.2-litre aluminium cylinder. Its 175 mm diameter matches S45, while the 493 mm body adds capacity with a listed weight of 9.9 kg. It is narrower than the S53 despite their similar overall size.
Consider before buying
The specified buoyancy becomes positive near the end of the fill: +0.4 lb at 500 psi and +1.2 lb empty. Valve and rigging choices alter the assembly. The manufacturer page has no verified exact-model photo, so a logo is no longer shown as the product.
Our take
Compare S50 with S53 when diameter, weight and near-empty buoyancy matter more than the small capacity difference. The choice still depends on the full rig and gas plan. Search results included old or differently sized cylinders, not an eligible exact-current-model overall rating.
