SDI Divemaster | Professional DIR Leadership Course

Become the Leader Others Trust.

The SDI Divemaster Course at XR Explorers isn’t just about getting a professional certification card—it’s about becoming a true ambassador for safe, team-oriented diving. As the first tier of the professional program, upon successful completion of this course, graduates may assist an active SDI Instructor during approved diving courses. Furthermore, you will be qualified to supervise and conduct dives for certified divers, and plan and execute emergency procedures appropriate for the diving environment and activities.

The XR Explorers Standard: DIR Exclusive

This is a leadership course you won’t find anywhere else. It is created and taught exclusively utilizing the DIR (Doing It Right) philosophy. At XR Explorers, DIR isn’t optional—it is the foundation of every dive we make. We build leaders who demonstrate precise buoyancy, perfect horizontal trim, and disciplined team protocols. To support this high standard of safety and physiological awareness, all your training dives will be conducted using Nitrox 32% gas, and your tuition covers all boat and pool access fees.

Expect Rigorous Training

We are completely honest about our standards: We do not certify guides who meet the bare minimum. This is not a quick "zero to hero" vacation course. You will spend at least 10 to 14 intensive days with us.

• Intense Theory & Duration: A minimum of 40 hours of training, diving deep into leadership psychology, group management, and complex dive planning.
• In-Water Mastery: You will complete a rigorous schedule, including guiding a minimum of 4 dives with varying sites and environmental conditions. You must also pass demanding watermanship evaluations, such as an 800-metre swim with mask, snorkel, and fins non-stop without the use of arms in less than 17 minutes.
• Rescue Readiness: You will demonstrate your ability to handle emergencies by bringing a diver, simulating unconsciousness, up from depth, not greater than 6 Metres/20 Feet, and swimming them 100 Metres at the surface in less than 4 minutes.
• The Result: You will not just "pass"; you will earn the profound respect of your peers and the right to lead.

Real-World Experience: The Shadow & Assist Program

Earning your certification is just the beginning. We want you to be the best professional possible. Graduates of our Divemaster program gain exclusive access to the XR Explorers Shadow & Assist Program.

After certification, you are welcome to join our instructors to shadow and assist on any class you are certified in—completely free of charge. You only pay for your personal logistical expenses during these dives (gases, pool, and boat access). It is an unparalleled opportunity to build real-world teaching experience, log hours, and refine your professional skills under the guidance of our senior team.
