Posted on Apiradee PongsathabordeeTrustindex verifies that the original source of the review is Google. ไป Fundive Freedive กับครูเต้ยพาหาจุดสวยๆดำกันแบบปูพรม เนื่องจากเอาGoproไปด้วยอันไหนปลาหายากปลาน้ำลึกต้องลงเร็วและลึกจริงๆครูเต้ยดำตามถ่ายให้เลย ที่Big Bubbleบรรยากาศไทยอบอุ่นมากๆร้านอื่นทั้งไทย/ฝรั่งไม่ได้แบบนี้เลยรู้สึกโชคดีมากที่เจอที่นี่ขอบคุณครูเต้ยมากค่ะ I did 2 fundive freedive trips with the instructor Toei. He ensured our dives were nice and thorough. When we encountered rare/deep water fish which required a swift and greatly deep dive he grabbed my GoPro filming them immediately. He had gone an extra mile to ensure I had wonderful experience the entire trip and I did. Highly appreciated instructor Toei.Posted on May MoonjaiTrustindex verifies that the original source of the review is Google.

It was a really fun experience! dive mentor here is super focused and supportive. Even when I panicked and didnt want to continue, he kept encouraging me and made me believe I could do it. Everything he taught before my first dive was very helpful, especially when I had to do things on my own in the end—and I did it! I would definitely recommend this place. It was also really nice to have Kru P’Champ helping me. Finally, I can truly enjoy scuba diving!Posted on Seenam LeeTrustindex verifies that the original source of the review is Google. ดำน้ำสนุกมาก คุณครูใจดี มีเพื่อนเยอะแยะ <3Posted on Rusnanee KareemaTrustindex verifies that the original source of the review is Google.

PADI Open Water, Kho Tao – Our Open Water Dive instructor, Dyan, was so friendly and patient with us novices. Small class meant we got lots of attention. I was also impressed with the diving school… read more for other reasons. Firstly, it is one of the only Thai owned and run dive school and has been established for 30 years. Secondly, their beach access and bar with basic bubble bungalow accommodation across the road made the whole experience more enjoyable.

Best Diving School – Best diving instructor – This was such a great experience, I had the best time with the best instructor, ICE, who made me feel very comfortable and safe. Everything was done in a very… read more safe way. Everything about the dive was reviewed first by my partner instructor ICE. It is a smaller diving school in a small town and this means that there are far fewer people who sign up than in the big cities. This makes it a cozy relaxed atmosphere with plenty of space on the boat. My biggest recommendation to the diving school, instructor ICE, as well as his colleagues. I will definitely return.
