How we calculate scores →About this gear
S45 is a short, relatively broad aluminium cylinder with 6.4 litres of water capacity and 45 cu ft of air capacity. Its 450 mm length is useful to compare against taller cylinders, while the 175 mm diameter and 9.2 kg weight prevent it being mistaken for a narrow stage bottle.
Consider before buying
Catalina lists buoyancy moving from -2.8 lb full to +0.5 lb empty. The official page currently supplies a placeholder rather than an exact product photo; the previously assigned logo has been removed. Check local supply and valve options directly.
Our take
Consider S45 when body length is the main constraint and the planned gas requirement fits its capacity. S50 is the same diameter but longer and heavier. Older external specification tables differ on buoyancy; current manufacturer figures are used, without an invented rating.
