Open Water Course Schedule

What you’ll learn
- Knowledge development (theory)
Core topics include pressure and buoyancy basics, breathing and equalisation, dive planning, safety procedures, equipment use, and environmental awareness. You’ll complete knowledge checks and a final multiple choice exam.
- Confined-water training (pool)
You’ll learn and practice essential scuba skills in a controlled environment before moving to open water. Skills include equipment setup, regulator recovery, mask clearing, buoyancy control, safe ascents/descents, and out-of-air procedures.
- Open-water training dives (4 dives)
You’ll apply your skills in real conditions over four training dives. Training is performance-based: you move forward when you’re ready.

How we teach
- Small groups and coaching.
- We keep training focused and calm.
- Skills are repeated until you’re comfortable, and the pace is adjusted to the group.
- If you’re nervous about mask skills, equalising, or feeling “rushed,” tell us - these are common beginner concerns and we coach them step-by-step.
- Group size and supervision: We keep groups small and adjust ratios based on conditions and student needs.

Completing the course earns you the SSI Open Water Diver certification, a worldwide recognised diving license that allows you to dive up to a depth of 18 meters while accompanied by a dive buddy of a similar or higher certification level. This is equivalent to the Padi Open Water diving license that over the years people have come to know simply as 'getting my Padi'.
