 In the new age of remote learning and internet access, you can complete all of the academic requirements for your entry-level scuba diver certification online. CTSA has developed one of the most in-depth open water online courses in the industry.

Course Progression

  • Take your online course

    Our online course is more comprehensive than the average recreational class, giving you a more in-depth understanding of the sport of Scuba.

  • In water skill development

    Once you have completed your online training, we move to Confined water in a pool or pool-like conditions where you master your in-water skills.

  • Open water Dives

    The final session is your open water dives. Here is where you put to practice everything you learned online and in confined water training.
