Deep Blue Divers Koh Tao

Deep Blue Divers is truly the best dive shop in Koh Tao! From the moment I arrived, I felt welcomed with open arms. The shop is located close to the pier, which makes everything very convenient and relaxed. A huge thank you to Casey, Coray, Nico, and Joji. Such understanding, professional, and highly trained instructors and divemasters. I always felt safe, supported, and well taken care of. The equipment is excellent. Especially the wingstyle BCDs, which felt much more comfortable and improved my diving experience. I even was getting additional equipment for tyout and dive-computers are included. Casey made everything so easy. During several dives, we saw the different divesites around the island, thousands of fish and incredible marine life. The plankton night dive was absolutely magical. The best one I’ve ever done! Whenever I had questions or small problems, they were patient and helped me improve my skills and feel more confident underwater. The atmosphere was amazing, relaxed, positive, and full of good vibes. I felt truly cared for the whole time. Highly recommend Deep Blue Divers to anyone diving in Koh Tao!

Jo & Casey at Deep Blue Divers, Koh Tao are honestly amazing. I did a refresh dive and fun dive with Jo, then continued with the Night, Wreck, Deep, and Perfect Buoyancy specialties with both Jo and Casey. Every dive felt well-organized, safe, and genuinely fun. They’re both super professional, patient, and easy to dive with, and they really focus on skill improvement, not just ticking boxes. The Perfect Buoyancy specialty especially made a huge difference in my control and confidence underwater. Great briefings, solid equipment, awesome dive sites, and a really good, relaxed vibe at the dive center. If you’re looking for a place in Koh Tao that offers proper specialties and instructors who actually care about your diving — Deep Blue Divers is the one. Would 100% dive with them again.
