You access SSI e-learning before your arrival — online lessons and instructional videos available in English and French. This means your two days on the boat are dedicated entirely to practice.
2. Confined water practice and open water dives
You start in shallow water to master buoyancy and comfort underwater. Then, you complete 4 open water dives with a certified instructor on the dive sites of Koh Tao, applying what you learned in real conditions.
3. Knowledge assessment and Open Water SSI certification
Before earning your Open Water SSI Koh Tao certification, you take a test to validate your theoretical and practical skills. You leave with a certification valid for life, worldwide.
