What You Learn

The Open Water Diver course consists of three main phases:

  • Knowledge Development (online, home study, or in a classroom ) to understand the basic principles of scuba diving,
  • Confined Water Dives to learn basic scuba skills,
  • Open Water Dives to review your skills and explore!

If you've participated in a Discover Scuba Diving experience or resort course, the skills you learned may be credited towards a portion of the full Open Water Diver course certification.


You can start your adventure today at home or on the go with e-Learning on your computer, tablet, or phone.
