The PADI Open Water Diver course is, by far, the world's most popular scuba certification course. Millions of people have started diving as certified PADI Open Water Divers. Learning to scuba dive requires both knowledge development (facts, principles, concepts) and dive skills (techniques, methods). The PADI Open Water Diver Course online provides the knowledge development portion you need. You develop the remaining skills by actually diving with a PADI Instructor at your local PADI Dive Center or Resort.
