The fun part of the Nitrox diving course lies in the new opportunities it offers. Diving with Nitrox, which has more oxygen and less nitrogen than regular air, allows for longer bottom times and less fatigue after dives. It also provides greater flexibility to perform multiple dives in a day with less surface interval. Additionally, it facilitates more relaxed exploration and observation by reducing the need to constantly monitor no-decompression limits. The course also adds a technical and educational aspect by teaching about gas mixing and the proper use of equipment.
