Never thought I would get my underwater certification. After walking around the island of Koh Tao and talking to other dive shops, I was very satisfied with choosing Big Blue. Not only were they extremely accommodating, they were also very understanding and welcoming. They put you the diver first above anything else and you can tell they are very passionate about spreading the joy of underwater life. It was nice to work with a group of individuals who wanted you to succeed. My instructor Jackie was extremely supportive and took her time with me to make sure I understood every step. I would like to also say that I was very impressed with how environmentally friendly and respectful they were. I HIGHLY recommend this dive school.
