I finished my Dive master and Instructor training here from June to beginning of Sept 2026. I wish I could’ve spent more time here with the young, interesting souls here in this dive center. I spent unforgettable months here. It’s a lovely memory. I wish new DM or Instructors could have the same experience as I did.

I completed my PADI Open Water certification here as a complete beginner, and it proved one of the most rewarding experiences of my life. The team was professional, welcoming, and flexible, tailoring the course to my schedule and needs. What set this experience apart was my instructor, Isabella Pelosio. When psychological hurdles arose during the course, Isabella recognised them and knew precisely how to guide me through them. She was reassuring at every stage, ensuring that I felt safe, understood each skill, and progressed at a pace that allowed genuine confidence to replace anxiety. Isabella combines technical excellence, responsibility, and deep knowledge with a rare ability to reassure without ever diminishing the challenge. Her calm, attentive teaching gave me the security to push beyond my limits, while her genuine excitement at every underwater discovery made the experience all the more memorable. Thanks to Isabella, I did not simply earn my certification; I discovered a new world — and a new belief in myself. I recommend this diving centre without reservation, and above all, I recommend requesting Isabella. For any beginner or apprehensive diver, she is exactly the instructor you want at your side.

We went diving with Black Turtle dive and it was amazing. Ces was such a lovely person and took all time we needed. It was so Nice to dive, we didn’t do that ever before and she made it so comfortable. We didn’t know if we wanted to go diving next day but because Ces helped us Enjoy it that much we went for another day. Maria helped us that day and she is such a lovely person as well and so helpful. I would recommend everybody when you are in Koh tao go here and see for yourself how Nice it is.

I couldn’t have asked for a better experience for my Discover Scuba Dive with Claire! She made me feel completely at ease and made the whole experience so enjoyable. She was incredibly patient, supportive, and never made me feel pressured at any point. I had a few moments where I felt quite nervous, but Claire was always there to reassure me and help me through them. Thanks to her, I was able to relax, enjoy both of my dives, and I’m already looking forward to diving again in the future! The facilities were amazing, especially the pool, and I felt safe and supported throughout the entire day. I also loved the friendly atmosphere on the boat and getting to spend time with the other divers. If you’re thinking about trying scuba diving, I can’t recommend Black Turtle Dive enough! Everyone was so friendly throughout the whole process. It’s an absolute must-do experience, and you won’t regret it. A huge thank you to Claire and the whole Black Turtle Dive team for making it so memorable!!! 🥹🫶🏽
