Bailout gas.....how much is enough?

[Scubaal]

If you have ideco on iphone its fun to play with the different "what ifs" Really eye opening as to bailout mixes and size of bottles. As a person dives past 200ft. Two bailout mixes seem to work out much better when it comes to getting the diver out of the water.

From Ideco: 225ft/20min 10/50 trimix w/1.3 set point. Total runtime 67min.
Bailout using 21/35 and 100% O2 total runtime 96min. 124cf of 21/35 and 24cf of O2
Bailout using 21/35, 36% and 100% total runtime 67 min. 60.5cf of 21/35, 33.7cf of 36% and 18cf of O2

So for our deeper dives we are starting to carry 1-80cf and 1-40cf of mix along with a third 30 or 40 of 100%. In some stiutations 2 40's instead of the 40&80

We have moved away from the 1 1/2 gas need carried by the team (2 divers) to carrying 100% of the individuals needs.
