The main feature of a semiclosed rebreather is the reduced bubbles and silence it offers, which allows you to get closer to shy wildlife.

What You Will Learn

Through the Semiclosed Rebreather Specialty course you learn the special procedures for semiclosed rebreather scuba diving. This includes special dive planning, organization, procedures and potential hazards, many of which differ significantly from conventional (open circuit) scuba.

It specifically focuses on the features, accessories, maintenance and proper use of the Draeger Semi-closed Rebreather. You make at least one confined water dive and at least three open water dives to learn:

• Advantages and disadvantages of the rebreather
• Assembly, disassembly and maintenance.
• Dive planning and emergency procedures with semiclosed rebreathers.

This is a challenging and very exciting course that includes four training dives over at least two days. During your first open water dive you'll practice line handling, reel use and emergency procedures without entering a cavern. But, for your next three dives, you're headed into the cavern, staying within the light zone and 40 metres/130 feet total distance from the surface.

What You Will Learn

• Cavern navigation and line protocols.
• Planning, organization, techniques, problems and hazards of cavern diving.
• Special equipment use, such as lights, guidelines, reels and redundant breathing systems.
• Air sharing, disorientation, silting, line problems and other emergency procedures specific to cavern diving.
• Silt prevention, buoyancy control, air management and emergency procedures.
• Depth and distant limits for cavern diving.

Your Next Adventure

The Peak Performance Buoyancy course will help you perfect your buoyancy skills for cavern diving. Many cavern and cave divers are also Enriched Air Nitrox certified so that they can enjoy more time exploring underwater. If you love cavern diving you may be interested in the Discover Tec Diving experience, which lets you try out basic technical diving equipment and skills to help you see if you want to learn more about going beyond recreational diving limits.

What You Will Learn

• Search and recovery dive planning, organization, procedures, techniques and how to deal with potential problems.
• How to locate large and small objects using search patterns.
• How to use a lift bag and other recovery methods.
• Limited visibility search techniques.
