PADI Open Water Course PART B

The PADI Open Water Diver course is the world’s most popular scuba certification, allowing divers to explore depths of up to 18 metres anywhere in the world. Whether you're looking to dive on holiday, explore UK dive sites, or begin your journey in scuba diving, this course provides you with the essential skills and knowledge to dive safely and confidently.

How the Course Works

The PADI Open Water course is divided into two parts:

PART A – Confined Water & Theory (Open Water Referral)

In PART A, you’ll learn the fundamentals of scuba diving in our heated training pool in Chertsey. This session, guided by one of our expert instructors, focuses on core diving skills, safety procedures, and equipment use.

Online eLearning theory – complete at your own pace before your pool sessions
