How Training Works
Knowledge Development
Build an understanding of equipment, the underwater environment, pressure, physiology, dive planning and responsible diving practices.
Confined-Water Coaching
Develop and refine core scuba skills in controlled conditions, with time to understand each skill and repeat it reliably.
Open-Water Experience
Complete a minimum of four supervised dives and apply your skills in real diving conditions. SDI requires at least 80 minutes of accumulated underwater time.
Training is performance-based. Meeting minimum attendance, time or dive numbers does not guarantee certification; all required knowledge and skills must be demonstrated consistently.
Skills and Knowledge You Will Develop
Continue Your Development
Your next step should match your interests, recent experience and in-water foundations. We can help you choose an appropriate progression rather than collecting certifications without the experience to support them.
