forgot to ask about bottom times. Are you trying to stretch a 30 minute dive to 35 minutes? Or are you whining about having to surface after 70 minutes?

Just noticed this. Ah...scuba diving. The only sport where grown men will brag about how small their S.A.C is.His S.A.C. Is larger than mine
We have choice of either 100 cubic foot air tanks or 80 cubic foot nitrox tanks.
Ok hang on a sec. I just noticed this in your original post. Seems like you have your solution. You dive the 80s and he dives the 100s. Whats the problem?

Actually, as Steve_C points out, the buddy needs approximately 40% more air to match the original poster's air consumption. If he uses a 100 cu.ft. tank and the OP uses an AL80 (really 77.4 cu.ft.) then the buddy only has 29% more air. The buddy's SAC rate will still be the limiting factor.
Right, so he shouldn't bother with nitrox in the 80 if his buddy is diving the 100 on air.Ok hang on a sec. I just noticed this in your original post. Seems like you have your solution. You dive the 80s and he dives the 100s. Whats the problem?
