I had an amazing experience doing the 3-day open water scuba course with Shai!! He was extremely knowledgeable and encouraging, and I felt confident and safe the whole time. Each day was brilliant, learning and practicing new skills while having some fun at the same time. I couldn’t recommend this experience any more highly!

Amazing club, the vibe is infectious and welcoming—we felt right at home from the very first minute. The staff is incredibly professional, kind, and warm. Andrew, Katie, Shay, Chris, Kayla and Cha - thank you for an unforgettable experience!
