Why Choose the RAID CCR Normoxic Trimix Diver Course?

The CCR Normoxic Trimix Diver program trains you to safely plan and conduct advanced decompression dives to 60 metres / 200 feet using normoxic trimix on your specific rebreather. This course expands your depth range, enhances your gas planning capability, and strengthens your ability to execute long-range decompression dives with precision.

What This Course Helps You Achieve

  • Deeper, safer range: Extend your capability to 60m using normoxic trimix.

  • Advanced decompression: Learn to manage extended deco profiles up to 60 minutes of mandatory decompression.

  • Enhanced safety: PO₂, END, and bailout gas limits ensure safe mixed-gas exposure.

  • Unit-specific mastery: Train completely on your own CCR model for absolute precision.

  • Real-world readiness: Learn skill sequencing, bailout confidence, and situational control at depth.
