We had an absolutely great experience with BB Divers on Koh Chang! We made two dives with the bottle and were accompanied by Mr. Chang is with us. He was incredibly friendly, patient and explained everything to us very understandably – both on land and in the water. Even during the preparation we felt in good hands, and during the dives there was always a sense of security. Underwater it was just breathtaking – we could see so many different fish, corals and other sea creatures. The view was great, and the whole atmosphere was just relaxed and professional at the same time. For us it was an unforgettable experience and definitely one of the highlights of our stay on Koh Chang. We can do BB Divers and especially Mr. Chang really warmly recommend – whether beginner or advanced, you are in the best hands here! 🌊🤿

Had the best day today with BB divers! Steve was our instructor and he made both myself and my partner feel very comfortable in the water! His instructions were clear and you could tell he genuinely cares about your safety and giving you a great experience. Steve made me feel very safe, which was my biggest concern about booking a diving day. Staff were great, lunch was light and overall a day that was relaxed but also gave us a great experience! Thanks Steve!

We went out with Geoffrey the first day and had such a good experience we went for the wreckdive the day after. Very experienced and friendly crew at BB, and the equipment was excellent, too. Food was delicious and also had a tasty vegetarian option!

Had such a great day out diving with BB Divers on Koh Chang! Steve and Fred were awesome — super friendly, fun, and really knew their stuff. The dives were amazing, and the aquarium was open just like Steve said, which was a nice surprise. Everything went smoothly from start to finish. We’re super happy with the whole experience and can totally recommend BB Divers!

We joined two dives to Koh Rang with BB Divers, departing at 9 am and returning around 4 pm. The whole experience was well organised — from booking and hotel transfers to the rental equipment, everything ran smoothly and on time. The dive boat BB4 was spacious, comfortable, and functional, making it easy to gear up and relax between dives. At Koh Rang, the dive sites were relatively shallow (max depth about 13m) but enjoyable, with healthy reefs and plenty of reef fish to see. Visibility ranged from about 5 m to 15 m depending on the site and conditions. Overall, a professional and well-run operation with good logistics.

Steve very kind and professional! He is passionate in leading every diver and will answer you clearly if you have any questions. Another coach is also very careful - before water, he will carefully check the BCD and all equipment. Thank you very much Steve for bringing us a wonderful and fun diving experience! We will definitely be back for diving in the near future!

I expected a professional dive and that is what I got. Oscar was my Divemaster and briefed me all along the way. Oscar was very knowledgeable, very professional and tended to my every need. I had been 26 years since I've strapped on the tanks. After I completed a strong refresher course in the states I was ready for Koh Luan and Koh Yak Yai . Oscar did see that I was struggling with sea sickness and provided help along the way. I hope those reading this, will have Oscar as there Divemaster, it will be a most enjoyable and safe dive

I was taking diving lessons with the diving instructor Joe Pawsey. He explained everything so I understood it. He is a great guy and teacher. Would recommend 100%

Refresher fun dive with Oscar was very good. We felt safe during the whole dive. Oscar explained everything clearly and his tips were helpful. The diving equipment and boat from BB divers is in good condition. The lunch they serve aboard is very decent. They also offer a free pick up service from the hotel. The booking was very easy, we just walked into the dive shop and Pawel was very supportive.
