Start where you are

No experience needed. This is where every diver begins.
Continue your training
Specialty courses that sharpen your skills and open up new diving.
Perfect Buoyancy
Master your buoyancy and dive effortlessly
Buoyancy is the skill that separates good divers from great ones. This specialty teaches advanced techniques so you hover with ease, protect the reef, and squeeze more bottom time from every tank.
Night & Limited Visibility
Explore the ocean after dark
The reef transforms after sunset. Learn to dive confidently at night and in low-visibility conditions, where specialized equipment and techniques reveal a hidden world of nocturnal marine life.
Science of Diving
The physics and physiology behind every dive
A comprehensive theory-only program that explores diving physics, physiology, decompression theory, equipment, and the aquatic environment. Essential knowledge that deepens your understanding and is required for most SSI professional levels.
Navigation
Dive smarter with compass and natural navigation
Always know where you are. This specialty gives you the advanced skills to navigate underwater with confidence — using a compass, natural features, and proven patterns to leave and return to your starting point.
Enriched Air Nitrox
Dive longer and safer
The most popular specialty in diving. Learn to use oxygen-enriched gas mixes up to 40% to extend your bottom time, shorten surface intervals, and add a margin of safety — recognized at dive centers and liveaboards worldwide.
Marine Ecology
Become an underwater naturalist
Understand the living ocean. This program introduces the science of marine ecology — the relationships between organisms and their environment — so every dive becomes richer and more meaningful.
Go professional
Turn your passion into a career guiding and assisting divers.
Dive Guide
The first step into a dive career
Your entry into the professional ranks. As a certified Dive Guide you can lead certified divers on recreational dives, conduct site briefings, and assist instructors — the foundation of every dive professional's career.
Divemaster
Lead, assist, and inspire
A respected professional rating that builds on Dive Guide. Divemasters take on greater responsibility — leading divers, assisting instructors, and acting as a role model — backed by deeper science and more logged experience.
