Great open water program

This diving club was really nice, y instructor Oni was amazing. He was clear on the lectures and was passionate about teaching. When diving he always made sure we were safe and that we didn’t miss any of the amazing wild life.

Amazing first time experience

A million thanks to Malcolm for an amazing 3-day SSI Open Water course at Koh Tao Scuba Club! Professional, positive, fun, and super well-structured - exactly the kind of instructor you hope to have for your first serious diving experience. Even in our group of four, everyone got plenty of individual attention, which made a huge difference and helped us feel safe and confident. The skills training in the pool and later in open water at a depth of 6 meters was clear, gradual, and very well supervised. Malcolm was endlessly patient, even when something didn’t work out several times in a row. What impressed me the most was his empathy and ability to notice someone’s worries even before they fully realized it themselves - that’s next-level pro stuff. I’m really glad I had the chance to learn from the best and to discover the underwater world without fear. There was definitely fear before diving into the unknown ocean at 12 and 18 meters for the first time, but the clear diving plan, instructions, and great underwater communication left no room for doubts – only space for excitement and wonder. Thanks for “infecting” me with this new addiction – diving will now make all my future travels even more exciting! If I’m lucky enough to return to Koh Tao one day, I’ll definitely come back for more lessons or a fun dive with Malcolm. Greetings from Lithuania! 🇱🇹 P.S. Big shout-out to photographer Hun for capturing our happiest diving moments - I can’t stop looking at the photos, and we’ll gladly be sharing them with friends and family. The photos were ready the very next day after the course. Amazing service!

Scuba open water

I was with Oni, the course was excellent and very fun! Would do it all over again :) First day was in the pool, then we went to the sea on second and third days.

Balanced and professional- perfect mix of fun and learning

I completed both my Open Water and Advanced courses with Oni, and it was an excellent experience. He strikes the perfect balance between being fun and being a strict, disciplined instructor. He focuses strongly on the lessons that truly matter while diving and never compromises on safety. I also loved diving with the team and am very happy to be certified under his guidance.
