SSI Extended Range Trimix – Advance Your Technical Diving Limits

Explore Deeper Dive Sites Safely with Trimix

The SSI Extended Range Trimix course introduces you to diving deeper using trimix—a gas blend of oxygen, nitrogen, and helium. Designed for technical divers looking to extend their dive depth safely, this course allows exploration down to 45 metres with reduced narcosis and enhanced clarity underwater.

Throughout the course, you will develop crucial technical diving skills. You’ll learn to manage helium-based gas mixtures, master decompression procedures, and safely handle technical diving equipment under the guidance of experienced SSI XR instructors. With this training, you’ll confidently dive deeper while significantly improving safety and control.

Why Choose the SSI Extended Range Trimix Course?

This course provides divers with the opportunity to:

• Reduce Narcosis: Helium mixtures minimise nitrogen narcosis, significantly improving clarity and safety.

• Enhance Dive Planning: Master gas selection, decompression planning, and trimix dive logistics.

• Develop Technical Proficiency: Gain hands-on experience with twinsets, stage cylinders, and advanced dive gear.

• Expand Your Limits: Safely conduct deeper dives (up to 45m) with improved bottom time and reduced risks.

Ideal for technical divers advancing beyond recreational depths, this SSI course sets the foundation for future hypoxic and technical trimix diving.
