Get Smart

Master all the important academic information. Traditionally, this required several hours of formal classroom training. Now, through online training, you can complete this phase through self-study, at your own pace, in the convenience of your home or office.

Get Wet

For entry-level certification courses (as well as some continuing-education classes), the next step will be to complete your in-water skill-development training. This takes place in a swimming pool or similar body of confined water, under the supervision of an ERDI Instructor.

Go Diving

The final step is to complete the required number of open-water training dives under the supervision of your ERDI Instructor. Here you will apply what you have learned during your academic and skill-development sessions, while learning practical lessons that can only be gained through real-world experience in open water.
