Scuba Cylinder Specifications for Buoyancy and Weighting Calculations
When scuba divers calculate their buoyancy with an aluminum cylinder, it is essential for them to know the relative buoyancy characteristics of their chosen cylinder – at full pressure capacity and also at their minimum reserve (500psi).
The following tables provide buoyancy information on the common Luxfer aluminum tanks.
Incorporating these figures into your weighting calculations will help improve your comfort and control when scuba diving.
