Hi everyone:
I am planning a deep dive 120 ft and then a shallower dive at 70 ft. My plan was to use air first and then switch to Nitrox on the shallow dive. Would that the best route or would it be better to start with Nitrox first? The mix will be 30% and the MOD is 121. Since I would be REALLY close to my MOD, I am more inclined to start with air first. Thoughts? Ideas? Suggestions?
