It’s that simple! Now, go dive the world with your SDI certification.

Step 1

Get Smart

eLearning for Scuba Diving

Start your SDI Open Water Scuba Diver course and master all the important academic information online or at your local dive shop. You can complete this phase through self-study, at your own pace, in the convenience of your home or office.  All eLearning courses work on mobile and tablet devices too.

Step 2

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 SDI Instructor.

Step 3

Go Diving

Open Water Diver

The final step is to complete the required number of SDI open-water training dives under the supervision of your SDI 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.
