SDI Divemaster
Professional Rating · Go Pro · Diver to Dive Leader
Stop being a diver and start being a dive leader. The SDI Divemaster program is the first professional rating in SDI recreational diving. It qualifies you to guide certified divers, brief and manage groups in the water, and assist instructors, and it's the doorway to teaching. This is a serious step up: you'll need to be 18, hold Advanced Adventure and Rescue Diver certifications, carry current CPR, first aid, and oxygen provider training, and have at least 40 logged dives. Because it's a professional course, you'll dive your own complete kit.
Veterans can put their GI Bill toward their training, and families can use ESA or ClassWallet funds. See if you qualify.

SDI Divemaster Program
This is where you stop being a diver and start being a dive leader. The SDI Divemaster program is the first professional rating in SDI recreational diving, and earning it means you're qualified to guide certified divers, brief and manage groups in the water, and assist instructors while they teach. It's a serious step up in responsibility and skill, and it's the doorway to becoming an instructor. If you've reached the point where you want to lead the dive instead of just enjoy it, this is the program.
What a Divemaster can do
The rating opens doors that a recreational certification can't:
- Lead and guide certified recreational divers in conditions similar to your training
- Plan, brief, and manage a dive group in the water
- Assist an instructor during courses and student training
- Take the first step toward the Instructor Development Course
What you'll master
Divemaster training goes well beyond diving skill into the knowledge a professional carries.
- SDI standards, procedures, and the Divemaster code of ethics
- Dive theory at a professional level: physics, physiology, and dive medicine
- Dive planning and risk management for groups
- How to plan and brief group dives, and lead them well
What you'll demonstrate
A professional rating comes with real physical and leadership standards you'll meet.
- An 800-metre swim with mask, snorkel, and fins in under 17 minutes
- Watermanship and stamina expected of a dive leader
- Managing a dive group in the water, start to finish
- Applying your rescue and emergency skills in a leadership role
