Go Beyond the Limits
Experience Recreational Decompression Diving.
Many divers eventually reach a point where they want to stay a little longer, explore a little deeper, and push beyond the normal no-decompression limits—without committing to the full demands of technical diving.
The Decompression Diving Program at Central Coast Divers is designed specifically for recreational divers who want to safely extend their dive profiles using the equipment they already know and trust.
This course provides the knowledge, skills and experience required to conduct limited decompression dives, using your personal dive computer, a recreational Total Diving System, and a single-stage cylinder.
During the program you will learn how to plan and safely conduct decompression dives:
• To a maximum depth of 40 metres
• Using an optimised Nitrox mix up to 40% oxygen
• With a maximum accumulated decompression time of 15 minutes based on a back-gas profile
• Diving with an equally or more qualified dive buddy
• Using either a recreational or sidemount Total Diving System
You will also develop advanced skills in gas management, dive planning, situational awareness, and decompression discipline, allowing you to extend your dives safely and responsibly.
This program is the perfect bridge between recreational diving and technical-style dive planning, giving you access to deeper wrecks, walls, and extended exploration opportunities.
