The SDI Open Water Scuba Diver certification is your entry point into recreational scuba diving.

Diving Theory: Understand the fundamentals of scuba diving, including pressure, buoyancy, physics, physiology, the aquatic environment, and the effects of breathing compressed gas underwater.

Equipment Mastery: Learn how to select, assemble, use, and care for your scuba equipment, including the BCD, regulator, cylinder, exposure protection, weights, gauges, and dive computer.

Buoyancy & Trim: Develop effective buoyancy control and proper body positioning to improve comfort, air consumption, stability, and environmental awareness.

Dive Planning & Safety: Learn how to plan recreational dives, monitor your air supply, understand depth and time limits, use the buddy system, and respond appropriately to common diving situations.

Underwater Navigation: Develop basic navigation skills using natural references, compass techniques, distance estimation, and underwater communication.

Emergency Skills: Practise essential emergency procedures, including out-of-air situations, alternate-air-source use, controlled ascents, and basic rescue techniques.

A specialty SDI course. Scuba diving with enriched air nitrox gives you more no decompression time, especially on repetitive scuba dives.

You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session, and two optional (or required) scuba dives, you’ll:

• Discuss managing oxygen exposure.

• Practice analysing oxygen content in your scuba tank.

• Set your dive computer for diving with enriched air nitrox.

The SDI Advanced Diver certification is designed for certified recreational divers who want to broaden their diving knowledge, develop additional specialty skills, and build real-world diving experience.

Specialty Development: Complete four recognised specialty certifications to expand your knowledge and skills across different areas of recreational diving.

Advanced Diving Skills: Develop greater confidence and competence through specialty training covering areas such as deep diving, navigation, wreck diving, night diving, drift diving, advanced buoyancy, or other available specialties.

Diving Experience: Build practical experience through a minimum of 25 logged open-water dives, gaining exposure to different environments, conditions, and diving situations.

Dive Planning: Strengthen your ability to independently plan recreational dives, including gas management, equipment selection, navigation, depth and time management, and appropriate emergency planning.

Equipment & Configuration: Gain experience using equipment and configurations appropriate to your chosen specialties while developing good equipment-management and preparation habits.

Continuing Education: Use your specialty certifications as a foundation for further recreational training, including Rescue Diver and additional specialty programs.
