The air tastes of salt and diesel at the Mae Haad pier as the ferry shoves off for Koh Tao, and the instructor’s calm voice cuts through morning chatter: breathe slow, communicate clearly, and trust your kit. Over three days students move from classroom quizzes on Samui to shallow confined sessions at Koh Nang Yuan, then into open-water sites around Koh Tao where coral gardens and sleepy reef fish test new skills.
