Dino’s review - Excellent experience, I throughly enjoyed my time on the 3 days open water scuba diving. My instructor Dino’s was very thorough and is excellent at explaining everything. I would highly recommend Scuba club on Koh Toa!

Dinos great instructor - I had an amazing time doing my open water diving with our instructor Dinos. He was very thorough, kind and patient. He explained everything in depth, was super patient in the pool until we learnt all the skills perfectly so when we tried under the sea we did great (in my opinion) 😂. Furthermore, any issues under the sea , for example me struggling to find my neutral buoyancy he took his time and made sure I felt comfortable and I was able to nail it. My friend ( Finn) struggled with his equalisation... he was patient so he didn't feel rushed. Joe my other friends strap came loose and he adjusted. He carried this all out calmly and made you feel at ease... there were other things but just some examples. He was also very informative about Marine life. I was very confident in my exam all thanks to his explanations throughout the course. I also feel very happy to sort my equipment on my own and understand all the components, for next time I go diving. Lastly and most importantly, thankyou Dinos for making me feel comfortable and helping me complete this course

Open Water Diving Witz Kat & Yeray - I completed my Open Water diving course and I’m so happy and grateful that Kat and Yeray were my instructors. They truly did an amazing job! I struggled a lot in the beginning and often felt panicked while diving, but they helped me overcome my fear and were incredibly kind and patient with me. Not once did I feel like they were annoyed, even though I needed a lot of time to understand each skill. I highly recommend this dive school and I’m very thankful that I had the chance to learn how to dive there. I will definitely come back in March to do my Advanced course with them.

Open & Advanced Water Diving - The 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’ - I 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!

Koh Tao Scuba Club Open Water Diving - Everything about the course was very good. It was organised very well with everything from hotel drop off/pick up, equipment etc. Ae was an excellent instructor who explained everything very well and helped us stay calm. I felt very safe diving with her and it was such a cool experience.
