Nitrox Trimix Cave Mine Wreck CCR Sidemount DPV Blending



The International Association of Nitrox and Technical Divers has been at the cutting edge of technical 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.

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 UK and across the world.

All our programs, from entry level upwards, equip a diver with the skills and knowledge to become a safe, responsible and self-sufficient diver. 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.
