The SSI Open Water Course is the first step into the world of scuba diving. It is designed for beginners who want to learn how to dive safely and comfortably while discovering the underwater world.The course is usually completed over 3 days and includes three main parts. First, the digital theory, which you can do online at your own pace to learn the basics of diving, equipment, safety, and how the underwater environment works. Then you will practice important skills during confined water sessions (pool or shallow water) to become comfortable using the equipment and breathing underwater. Finally, you will complete four open water dives in the ocean, where you apply everything you learned with your instructor.By the end of the course, you will receive your SSI Open Water Diver certification, which allows you to dive up to 18 meters anywhere in the world with a certified dive buddy.It’s a fun and exciting course that opens the door to a lifetime of underwater adventures.

SSI Enriched Air Nitrox (EANx) SpecialtyThe SSI Enriched Air Nitrox (EANx) Specialty is one of the most popular diving courses, allowing divers to use breathing gas with a higher percentage of oxygen than standard air. By diving with Enriched Air Nitrox, divers can extend their no-decompression limits, reduce nitrogen absorption, and often enjoy longer or safer dives.During the course, you will learn how to safely plan and conduct dives using Nitrox mixes, typically EAN32 or EAN36. The training focuses on understanding the benefits and limitations of enriched air, how to analyze the oxygen content in a tank, how to set a dive computer for Nitrox, and how to calculate the maximum operating depth (MOD) for different gas mixtures.A key part of the course is learning oxygen exposure limits, dive planning, and safe handling procedures when using enriched air. Divers will also practice analyzing their tanks and properly labeling them before diving.The SSI Enriched Air Nitrox course is usually completed in half a day to one day and is mainly theory-based. Some dive centers also include optional Nitrox dives to practice using the gas underwater.
