Get Smart

Most students complete this portion through SDI’s online learning platform at their own pace using a computer, tablet, or mobile device.
Get Wet

Next, you will complete your in-water skill development in our heated on-site pool or another confined-water environment under the supervision of an SDI Instructor.
During this training you will learn and practice essential scuba skills such as buoyancy control, regulator recovery, mask clearing, and underwater communication.
Training may be completed in different formats depending on the class schedule you choose.
Go Diving

The final step is completing your open water certification dives under the supervision of your instructor.
These dives take place in a local open-water environment where you will demonstrate the skills you learned during training and experience real scuba diving conditions.
Once completed, you will earn your SDI Open Water Scuba Diver certification.

In recreational diving, Nitrox is referred to as any gas where the mixture of oxygen is greater than 21% thereby reducing the nitrogen content to less than 79%.
You’ll learn in your Open Water course that decompression sickness is caused by nitrogen bubbles forming in your body tissues. Breathing a lower percentage of nitrogen (or a higher percentage of oxygen) allows less nitrogen to build up in your body and therefore increasing your decompression limits and decreasing the risk of decompression sickness.
