About IANTD

The International Association of Nitrox and Technical Divers has been at the cutting edge of diver training for more than 20 years.

From the first nitrox course in the world to our Tek Lite programs which allow for reduced narcosis in the entry-level tech depth range, through to CCR Cave and Expedition Trimix, we've been setting the standard since the very beginning

In 1985, we released the world's first enriched air diver certification - 10 years before other agencies followed suit. Since then, we've stayed at the very forefront of diver education, leading the way so that others may follow.
