Koh Tao Divers truly offered one of the best learning experiences I've ever had. The XR Sidemount Course was organized professionally, maintaining a perfect balance between education and enjoyment. I must mention my instructor, Naomi, who demonstrated commendable expertise and patience throughout the course. Kudos to the entire KTD team for creating such an amazing environment. Highly recommended!

The most professional dive shop I've ever been to. I did the extended range sidemount course with Israel. The niveau of the course was very high with a lot of attention to detail. The skills training was also performed in a very serious manner clearly indicating the importance of savety and why we train those skills. For anyone considering courses I can highly recommend KTD, especially when it comes to caverns, caves, wrecks and mines they are the best on the island. I will do further tech courses at their shop. 10/10 experience!

Did my extended range sidemount + advanced wreck with ISRAEL!!! One of the best instructors I've met, super relaxed and funny, but really focused on safety and following proper procedures!!!The worst part was that the course had to finish...

Thank you again ISRA and ko tao divers for everything:)

Some experiences rewrite the books. Having Alfonso, Isra, Rolo and Jordi as Extended Range instructors was incredible. Such an amazing team to work with, full of knowledge and valuable insights. A very rewarding and revealing experience. They are so passionate about what they do, that truly brings out the best out of yourself. These gentlemen will give everything they have got, so every moment is a learning experience. The level of performance, preparation, commitment and mindset of these guys really separates them from the masses. They are excellent in all they do. It has been amazing training with these guys! Looking forward to dive with this team once again!
