The PADI Open Water Diver course includes three parts: Knowledge Development, Confined Water Dives, and Open Water Dives. Knowledge Development covers the principles, concepts and terms you need to know for dive safety and enjoyment. During the Confined Water Dives, you learn and practice scuba skills in a pool or water with pool-like conditions. You’ll enjoy making one or more minidives, which take you through the same steps you follow when you make open water dives. To complete training you practice, apply and demonstrate what you learn during four Open Water Dives at a local dive site.
