5.00The team at Koh Tao Scuba Club are professional, fun, and fantastic instructors. Originally signed up for the open water diving certification and then chose to complete the advanced open water certification with KTSC. The daily lunch provided was delicious, and the complimentary tea and pineapple between dives helped with energy and hydration. Our group had Nui as our instructor and he was fantastic. Very happy to have received my scuba certifications through Koh Tao Scuba Club!
Fabulous’

5.00I was so nervous to scuba dive but knew it would be something I’d regret if I didn’t do it. We found Koh Tao Scuba Club and their communication put us at ease before we even met them. Oni our instructor was amazing, he kept us calm and gave us all the knowledge we needed. We had the best time thanks to Oni!
Great experience would highly recommend

5.00Safari has been an incredible teacher where he taught the basics of scuba diving in a pool and open water session. Zoe was freat during the fun dive where she repeated all the basics and ensured that everyone was safe and had fun.
