Open Water SSI Koh Tao, course structure in 2 days
The training takes 2 days and is divided into three main steps:
1. Theory and knowledge, online before you arrive
You access SSI e-learning before your arrival, with online lessons and instructional videos available in English and French. As a result, 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. In short, you apply everything you learned in real conditions.
Your 2 days, step by step
- Day 1: classroom from 9:00 to 10:30, boat departure at 11:00, first part of the confined water session in a sheltered bay (Mango Bay or Japanese Garden), then open water dives 1 and 2.
- Day 2: second part of the confined water session, then open water dives 3 and 4.
3. Knowledge assessment and Open Water SSI certification
Before earning your Open Water SSI Koh Tao certification, you take a short test to validate your theoretical and practical skills. You leave with a certification valid for life, worldwide.
