Crystal Dive was the highest standard of a dive school that I could ask for. Before coming to Koh Tao I was confused of what dive school to choose. So I went in person to the top 15 reviewed dive schools on Google. Crystal Dive bar far stood out the most. The instructions are very experienced, passionate and professional. The school have their own boats, dive pools, tones of high quality scuba diving gear. I only paid 19'000 Baht for advance and open water with free 5 days of twin bed accomodation (all to myself). My instructor was named Ana and my assistant instructor was named Lin. They two instructors were absolutely awesome. From day one Ana and Lin were very vibrant and enuthesiasic to ensure I had the best time with the most detailed training I could get out of the course. We done in person modules, online modules and training in the pool. Ana and Lin didnt make me feel rushed. They took their time until I was able to achieve the skill without mistakes and to the safest standard. Not once did I feel unsafe with Ana and Lin. I then went onto doing 9 open water dives (Advance, open water, Nitrox adv) and love every single bit of the course.I wouldn't go with any other dive school!Thanks Ana and Lin. You two are amazing ❤️👏Thank Crystal for holding a high standard with your instructors. They were great and should be appraised for their outstanding teaching skills 👏

Had a great Refresher scuba review session with Evan, after not diving for 2 years - the refresher was much needed! Thanks Evan for leading a fun and informative session whilst being a patience instructor. I’ve gained my confidence and ready to be back under the sea 🙂

Highly, highly recommend Crystal Dive in Koh Tao. Alex was a great instructor who really made us feel comfortable every step of the way whilst we were getting our open water certification. His passion for diving is contagious and made every dive great, despite the visibility not being great!

Last week I completed my Advanced Open Water certification and I can't be more happy that I made the decision to do it with Crystal Dive! A colleague of mine recommended me Crystal Dive and from the instant response to my emails to the quality of the teaching thru the infrastructure and equipment I'm more than happy! George was my instructor and he was awesome! I will be back and recommend you guys to everyone that wants to go diving! Diving is a life changing experience! Keep rocking!

We were really happy with Crystal Dive as our place to do Open Water PADI. Tom and Jonathan were excellent teachers, and for each step of the course we felt more confident in our diving skills. I am very happy with our decision to use Crystal Dive!The gear was great, they have their own pool which is very big. They also have 2 boats, so there is a lot of flexibility with regards to time.

5 star experience with Melanie! Her very calm demeanour was perfect for anyone who is anxious about getting their open water cert. She is very experienced and knowledgeable and makes sure everyone is comfortable. The room we got during our course was also so nice we extended our stay after the course! Thanks Crystal Diving

I have had the most amazing time learning to dive with Crystal Dive Koh Tao. I decided to do both my open water certification and speciality deep and Nitrox as I enjoyed the open water so much. Both were incredible and a pleasure to do especially with my instructor Kelvin who has got me hooked on diving!! I have learned so much over the past few days and I am looking forward to diving more and returning to Koh Tao!

I completed both my open water certification and deep and Nitrox specialty certifications at Crystal Dive Koh Tao and had the most fantastic time. My diving instructor Kelvin was exceptionally attentive, knowledgeable, encouraging and patient especially as i had never dived before and now completely love diving! Thank you so much Kelvin and the Crystal dive team.

Just completed my open diving course with crystal dive and had an amazing experience. My instructor was George who was very thorough and passionate. He guided me through the online learning and classes in depth which resulted in me feeling confident and knowledgeable on my first dives. I am really excited to explore more dives in the future and would definitely come back to do my advanced diving with George. I highly recommend crystal and requesting for George.
