About Us

Some History

We has been at the cutting edge of diver training for more than 30 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.

We offer a complete range of training courses from Open Water Diver through to Expedition Trimix using both open and closed circuit equipment and a full range of cave diver training programs. Our instructor trainers and instructors represent some of the very best technical divers and educators in the USA and all over the world.

All our programs, from entry level upwards, equip a diver with the skills and knowledge to become a safe, responsible, self-sufficient diver, in depth survival skills mentally and physically. It's a philosophy reflected in our Open Water Nitrox Diver course - why not start with the safety benefits of Nitrox from your very first dive? - and continues throughout all our training programs.

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.

Who We Are

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.

In 1985, Dick Ruthkowski, retired as the dive supervisor for the National Oceanographic and Atmospheric Administration, NOAA, and, together with other leaders in the diving community, formed IAND. Dick’s goal was to introduce the benefits of using Nitrox in many diving situations and to begin teaching safe decompression diving.

In 1991, under the leadership of Tom Mount, the organization grew into the leading technical training organization in the world, offering courses covering all aspects of sport diving. At the same time, the name was changed to the International Association of Nitrox and Technical Divers, IANTD, to better reflect the organization’s additional emphasis technical diving.

Today, IANTD has offices in over twenty five countries and instructors in more than 60 countries.
