Thanks Jay.
I told John we always plan for 10 ft increments anyway so 160 or 170. We were talking about doing "G" and the St James etc and got on the subject of gases. I liked the 21/35 schedule better and that is where the questions came from. I agree we are splitting hairs with this example. We are going to continue the planning Sunday after the dive if your interested. Quote:

Yepp I had 160-165 on the St James. Thats probably where we got the 165ft from.

Gas ranges changed recently according to GUE:
21/35 100-150 18/45 150-200 At least, this is according to the Tech1 course I was able to sit in recently. What you do, is, of course, entirely up to you and the team.

The MOD are different when using these standard gases for deco purposes. Generaly, we use 1.6 PPO2 for deco gases above 100 feet and 1.4 PPO2 for deco gases bellow 100 feet. Some dives may require changes. Deep deco gases may require a lower PPO2 du to CNS and OTU's which does not really affect us as we don't du these 25 hr epic dives like they do in Wakulla. Steve |

There's always a tradeoff, but t's better to spend a few more minutes on deco rather than push the CNS limits. The deco time difference between 18/45 and 21/35 is negligable anyway.
Many of us gave up 21/35 for 18/45 years ago just to cut down on the number of deicated cylinders we have ready to go and simplify the logistics of weekend travel planning. |
