How PADI Courses Work
PADI courses follow a clear three-part structure:
Knowledge Development
Complete the theory online via PADI eLearning – videos, quizzes, and knowledge reviews you can do anywhere, at your own pace. It covers essential dive physics, physiology, and safety principles.
Confined Water Training
Learn essential skills in a safe environment such as a pool or calm bay. You’ll practise mask clearing, buoyancy control, regulator recovery, and safety procedures until you’re completely comfortable.
Open Water Dives
Put those skills into practice on real dives under instructor supervision. Each dive builds confidence as you explore local reefs and learn to plan, navigate, and manage dives independently.
This flexible system allows you to do the theory before your trip, saving your ocean time for actual diving.

Discover Scuba Diving (DSD)
This half-day introduction is the perfect way to experience the underwater world without committing to a full certification course. You’ll start with a short briefing on basic scuba theory and equipment use before entering shallow water with your instructor. Learn to breathe underwater, clear your mask, and achieve neutral buoyancy. Once you’re comfortable, you’ll make a short open water dive – often encountering colourful fish and coral. It’s safe, fun, and often the first step towards full certification.
PADI Open Water Diver
The world’s most popular diving certification and your passport to the underwater world. The PADI Open Water Diver course consists of eLearning, pool sessions, and four open water dives. You’ll learn about dive planning, pressure effects, air consumption, and underwater communication. In-water training covers everything from mask and regulator clearing to buoyancy mastery and emergency ascent skills. By the end, you’ll be qualified to dive independently with a buddy to 18 metres, anywhere in the world.
