[License] training Enriched air SP course

Air with an oxygen concentration of about 22% to 40%, nitrogen used in normal diving is less likely to accumulate in the body than nitrogen with oxygen concentration of 21% Enriched air that reduces the burden on the body is a diving scene around the world It has increased a lot. If the unnecessary decompression limit is the same seismic intensity, it expands, so if you want to dive slowly it is the best air. The risk of decompression is also declining, and many divers use it. I will learn how to measure oxygen concentration, how to set a dive computer, and points to be aware of when breathing thick oxygen. It is possible to attend with Fun diving, so please try it.
