You are always tired after a day of diving… Dives do not last long enough because you run out of bottom time… You’re worried that you are diving too close to the no-deco limits. These are all concerns that can be resolved by diving with Nitrox, oxygen enriched breathing mixtures. Nitrox is highly recommended for all divers over forty, and it helps to give you those evenings back after a full day of diving! This course is a prerequisite for all technical diving. Requires two dives.
