Why Choose the RAID Decompression Diver 45M Course?
The RAID Decompression 45m course is the advanced progression for divers ready to transcend recreational limits and master the art of staged decompression. It is specifically designed for those who have mastered the fundamentals of the Deco 40 program and are ready to safely navigate the increased complexities of deeper, high-risk diving environments. By expanding your range to 45 meters, you gain access to spectacular, historically significant wrecks and unique marine life previously inaccessible to the average diver.
What This Course Helps You Achieve
Extended Range: Safely plan and execute dives to a maximum depth of 45 meters (145 feet).
Decompression Proficiency: Learn to manage mandatory decompression stops using optimized schedules.
Task Loading Mastery: Develop the ability to maintain stability and neutral buoyancy while managing technical equipment.
Optimized Ascent: Utilize a separate stage cylinder with up to 100% oxygen to reduce decompression times safely.
What You’ll Learn in the Decompression Diver 45M Course
Advanced Physics & Physiology: Master the complex gas dynamics and nitrogen loading associated with 45m exposures.
Technical Gas Planning: Learn to calculate gas volumes, including the one-third reserve rule for team safety.
Optimized Decompression: Understand the protocols for using high-oxygen nitrox for accelerated stops.
Emergency Response: Practice problem-solving in a technical environment, including long-hose gas sharing and backup mask deployment.
Team Protocols: Refine communication and positioning within a technical diving team.
