The PADI Open Water course is structured to cover three main components: knowledge development, confined water dives, and open water dives. Through a combination of online learning modules, classroom sessions, and practical exercises in a controlled environment, participants gain a comprehensive understanding of dive theory, equipment usage, and safety protocols.

Once the theoretical aspects are mastered, participants transition to confined water dives, where they practice essential scuba skills under the guidance of a certified instructor. These confined water sessions provide an opportunity to become familiar with dive equipment, practice buoyancy control, and learn essential safety procedures in a controlled environment.

The culmination of the Open Water course is the completion of four open water dives, conducted in a natural body of water under the supervision of an instructor. These dives allow participants to apply their newly acquired skills and knowledge in real-world diving conditions, while exploring the beauty and wonder of the underwater world.

Upon successful completion of the course, participants receive a globally recognised certification that allows them to dive independently with a buddy, to a maximum depth of 60 feet (18 metres). This certification opens up a world of possibilities for underwater exploration, from vibrant coral reefs and colourful marine life to historic shipwrecks and mysterious underwater caves.
