Learn the lingo! During the first phase of your PADI Open Water Diver scuba certification you develop an understanding of the basic principles of scuba diving. You learn things like how pressure affects your body, how to choose the best gear and what to consider when planning dives in order to have fun while staying safe. Your study resources are included in the eLearning program. The five knowledge development sections at the end of each of the five book chapters must be completed prior to your classroom session. Once you are done with your independent study, call us to book your classroom and confined water sessions!
