IANTD – International Advanced Nitrox and Technical Diving

Logo for IANTD International Association of Nitrox and Technical Divers_Logo

Up to a certain time, mixed gas diving and decompression gases were used almost exclusively for military or commercial purposes. Because it was quite simple and safe, mixed gases became more popular among some group of divers. In 1985 IANTD or International Advanced Nitrox and Technical Diving was founded to fill the gap and bring these techniques to the public.
