How we calculate scores →About this gear
S30 combines 30 cu ft air capacity with a 4.3-litre internal volume. At 133.4 mm across and 505 mm long, it sits between Catalina’s narrow S19 and longer S40. The listed 6.2 kg cylinder weight makes transport and mounting more substantial than its compact capacity suggests.
Consider before buying
Catalina lists -2.4 lb buoyancy full and -0.2 lb empty. Treat these as cylinder specifications, not a weighting prescription for an assembled system. Verify the actual valve, markings and inspection history before choosing a used example.
Our take
Compare S30 with S40 when the same body diameter is useful but a shorter cylinder is easier to accommodate. The smaller supply still has to meet the planned requirement. External charts corroborate the format; they do not provide an overall review score.
