TDI Trimix Diver IANDT Normoxic Trimix Diver

The IANTD Normoxic Trimix Diver Program is designed for divers who are ready to take the next big step into the world of deep technical diving. This course focuses on dives between 130 feet (39 meters) and 200 feet (60 meters) depths where breathing regular air is no longer safe due to the risks of nitrogen narcosis and oxygen toxicity.

To overcome these challenges, divers are trained to use helium-based gas mixtures (Trimix), which provide a clearer head, greater safety, and better control during deep dives.

Throughout the program, you’ll learn advanced dive planning, precise gas management, and the use of decompression gases to safely extend your bottom time.

The course includes a balance of academic theory, confined water skill development, and open-water dives that simulate real technical diving environments.

By the end of this training, you’ll not only expand your depth limit to 200 feet (60 meters) but also gain the confidence and competence to explore the deep with professionalism and safety.
