Go the Liquivision Harv's, then it'll be all set for when you venture into the world of rebreathers. C |

Craig,
Ratio Deco is an approximation to a deco schedule that uses specific breathing gases (Standard gases, Such as 21/35, 18/45, 15/55, 12/65, 10/70).
Hence you cant use Ratio Deco for the dive plan you have proposed below.
OK, so using standard gases then. For example: Travel gas 21/35 swapping to bottom mix 10/70 at 45m 100m for 10min on 10/70 75m for 5 min 60m for 5 min 50m for 5 min 45m swap to 21/35 40m for 10 min 35m for 15 min 21m swap to 50% 6m swap to 100% Deco schedule & runtime? |

Ratio
Deco: 1:3 @ 240'/72m - 300'/90m for 15/55 or 10/70
with TriOx 35/25, Nitrox 50 and O2 for deco
Set Point
270'/81m 1 : 3
BT DT Adjustments on the fly
10 30
15 45 + 10'/3m + 5 min
20 60 - 10'/3m - 5 min
25 75
30 90 Lost Deco Gas Double Deco time
35 105
40 120
Do 0.4 (40%) Deco time on O2 @ 20'/6m 20% of the time ascent to the surface
Do 0.4 (40%) Deco time @ 70'/21 - 30'/9m = 5 stops Do a S curve for Nitrox 50%
Do 0.2 (20%) Deco time @ 120'/36m - 80'/24m = 5 stops Do a S curve for TriOx 35/25
Notes:
O2 is always 12 min on O2 and 6 min off or Up
Always Backgas Break before gas switch (included in time) 80'/24m and 30'/9m
Do half of 120’/36m bottle time in 190’/57m-130’/39m range.
If you add 190'/57m bottle do not adjust times, this will only increase the effectiveness of
deep stops

Ian, why are you quoting in feet? Don't tell me you have been forced to give up the well proven metric system? Do you ask the girl at the cafeteria how much in US$, or do you convert it yourself and pay in greenbacks? JD |
