If Nitrox will not take you deeper than air, what will? I touched on a couple of possibilities previously - Trimix and Heliox, but I did not explain what they are, or how they work. I'm not a "Tech" diver; I'm not interested in going deep enough to actually need such gas mixes, and I've never taken a formal class in such things. But I do have an engineering degree, curiosity, and half a brain.
