Gas Planning Crib Cards

[Phil_Harris]

Hi All

Just a quick question, does anyone have or know where i can down load some crib cards for Gas planning ie: how much gas you require for the dive, how long your air will last etc.

Cheers in advance :-))

If you work on an SAC of 24lpm then you will use 2 bar/min at the surface in a 12L cyl.

4 bar/min at 10m
6 bar/min at 20m
8 bar/min at 30m ...

see? You don't need tables. You can do it in your head.
