Did my dm here.Been diving with different dive centers before, crystal is definitely the most professional one from training system to gears maintenance. They teach you how to properly get things done. Open water instructors would literally go through every single skill with you which is really really essential for new divers to get comfortable and enjoy the big blue. Encouraging but not pushing, crystal instructors are authentically happy to see every diver to keep blowing bubbles. Safety is also always at top level of all, oxygen tank and first aid kits, surface cover always ready for rescue and every roll call, good connection with local clinic and hospitals, caring crews and staffs…I’m forever grateful that I walked in crystal office and decided to do my dm here.The two and half month I spent on koh Tao at crystal is crystal precious with my DMC fellows. Special thanks to my mentor Oli who is there always by my side.Good vibe only 🙂

Best impulsive decision to take the open water course! In a group of 3 we were teached by the amazing Vera. Over 3 days we learned almost all the essential basics because of great teaching and support of the digital SSI(divers association) platform. First session in Crystal’s own private swimingpool (4m) and the next day we were out to the ocean and already so great sea life! Amazing overal experience with the best teacher (for low price and even free accomodation which is not 5 star but still really nice 😊) 👌👌

I completed a 3-day Open Water course with Kelvin Kyaw, and he’s by far the best scuba instructor! He was incredibly understanding and compassionate when I felt panicky, and his exceptional problem-solving skills and helpful tips helped me overcome my fear and complete the course smoothly. I highly recommend him to anyone looking to try scuba diving—Kelvin is a truly trustworthy instructor!

Tried the basic ride with Crystal Dive. My instructor was Evandro. He was very patient with me during the session. Thought I was unsuccessful in both of my dives, I really appreciate my instructor to try his best. Thankyou.

My experience with Crystal Dive Koh Tao was absolutely great! I originally came to the island for a refresher and some fun dives but was immediately convinced that this was the perfect place for my Advanced Open Water course. My instructor Melanie was professional, extremely thorough, knowledgeable and shared many tips for diving and the island. I really enjoyed every single dive and learned so much through her. I especially loved the perfect buoyancy dive and the sail rock dive! I felt very safe and cared for during my entire course. The atmosphere in the team was great, and the instructors clearly sparked the passion for diving of both students and fun divers. I'll surely come back and maybe even complete my Dive Master course with Crystal!

Did my SSI divemaster with crystal and really enjoyed the experience. The program was designed in which I got to improve my skill and knowledge in diving, also to experience and learn about teaching diving and interacting with students and real clients. The instructors are very knowledgeable and attentive, they are ready to help you if you have questions. It was also super lovely to be able to meet and spend time with the fellow dive master candidates there, we got to do a lot of fun dives together during our training, many beautiful memories created.

Such a fabulous dive centre! My friend and I were well looked after by Alex. He was very professional and thorough. We felt very comfortable, used great equipment and everything was communicated well. Would highly recommend!

I had the best time diving with Crystal! The centre is perfectly located on the beach with great accommodation on site. The staff members are all approachable, kind and professional which is really important for someone like me who was completely new to diving. Kelvin was my instructor for both my open water and advanced and he made the whole experience unforgettable. What can I say he was patient, super knowledgable and struck a perfect balance between fun, laid back but still super professional. Ciara was assisting us throughout both our OW and advanced courses and she was amazing!! She was always positive and bubbly and was a great addition to the group, she made the whole experience really fun!😊 We got photos taken by Vicky and couldn’t be happier with how they came out - so would highly suggest paying extra for that as it’s a memory you can cherish for life! Thanks again Crystal, until next time!

I did my Open Water course with Kelvin and am very excited! I was a little afraid beforehand, but the first day in the pool took my fear away completely, it's so cool what's possible! And diving is a lot easier than I thought. The small groups are great, but on the boats it can get a bit stressful because many groups start at the same time. On the first day in the sea you still have to practice a lot of skills, on the second day you are a little freer in diving and can relax more.The accommodation was free, great offer!

Really enjoyed my crystal dive experience with Michaella, she really put the effort to make sure we learnt everything and was very considerate, making sure equipment was clean also. Was so much fun, my open water course was also very good with Nina. 🤙👌😍 I imagine it is the case for all dive sites but only issue I found was the snorkel sometimes wasnt very clean with little time to clean that yourself before use. May be a good idea to provide soap so we can clean the goggles etc. ourselves before diving.

Was so lucky to have Michaella as my diving instructor for both the open water and advanced courses. This was my first time diving and I always felt absolutely safe underwater with her as the instructor. In only five days, my dive buddy and I, became super comfortable in the water with all the gear and we had so much fun. I have I only great things to say about this experience. An absolute highlight of my trip 🙏🏼🙏🏼🙏🏼 thanks!
