A relaxed confident diver is a safe diver who will enjoy exploring inner-space and pursue diving adventures for a lifetime.

International Association of Nitrox Divers, IAND, was formed in 1985 in response to the needs of the diving public. Up until that time, mixed gas diving and the use of decompression gasses was limited, in a formal way, to military and commercial divers.
