| Re: Deco Gas Options I (and my 2 dive buddies) did this dive all summer(25 min. at 230), documenting a new wreck here in lake Michigan. We all used 17/30-17/35, 50%, 100%. I personally like 40%, but we all used the same gas for our dives. I carry an 80 for nitrox, my buddies a 50's and a 40 for 02. |
