CCR's use pure oxygen in one cylinder and mixes are dynamic dependant upon depth.
I should've mentioned that I already understand some of the basics behind CCRs. Would the CCR course be able to cover the physics? Why would extensive deco training be needed, if I'm not planning to go into deco? Even the PADI OW air tables cover emergency deco to an extent. My dive computers (I'd carry at least two for CCR diving) should be able to handle it as well.
