Oh joy, some light reading :)
 
Sealark, when I dive Nitrox, I dive a Cochran. Granted I am using a Gemini which is their old gas integrated unit, but it is fully adjustable from 10% to 50% for gas No. 1 and 10% to 100% for gas No. 2 & 3, or something like that. It lets me either do a single cylinder "Maui" dive or I can do a two or three gas "deep" recreation dive with a nice Nitrox buffer on ascent. We usually do a 90 to 100 fsw down to bottom, sit for five minutes doing math problems and ascend during the scientific diver course to introduce the students to nitrogen necrosis. I dive it on 32% to reduce narcosis and Nitrox loading, and switch to 40% at 70 fsw to off gas faster on ascent. The Cochran tracks it all for me. Nice computer.
