When hear Nitrox, you might think it is equipment used for night diving. But it's actually a magical breathing gas that makes the risk of decompression sickness as low as possible.
It is especially suitable for elderly people, women and macho men who are at high risk of decompression sickness.
Since it is a diving that does not use air, it may have an extremely high-tech image, but it is a breathing gas that anyone can use if they can calculate + and –, × and ÷.
Nitrox divers may look cool!
