Just after some clarification here.
Im off to florida this month and hope to get a few days diving in. Im in the process of making notes/laminates to give a quick imperial<>metric conversion and other things.
What is a common size backgas cylinder used in the USA (in particular the keys)? Are these steel or aluminium ? What is the "standard" full pressure of these? Also, What is the usual "be back on the boat with xxxx psi" pressure operators tend to use ?
All my gauges are in metric, computer is staying set to metric, tables in metric etc so i need this sort of thing to work out what im breathing from and what guides to follow.
