We has a great Dividing day with Steve going to the Butterfly Rock and afterwards to the HTMS Chang. Three of our family are still quite inexperienced and Steve did a fantastic job explaining everything, helping with the equipment, do a proper buddy check and guide us under water. We all felt very comfortable and safe with him the whole day. Big thanks as well to Pawel from the office, he organized a trip for us to hop over to Koh Chang, stay there in their doorm, and then go back to Koh Chang. We finally had to cancel this due a familiar issue and there was no problem at all. Equipment is in a very good shape, boat is spacious and comfortable and food was very tasty as well. There are free drinks on the boat and they serve fresh fruit after the second dive. The pickup and return was also perfectly organized. The only thing that could have been better is the to visibility, but this is not in hands of the BN divers team, if not I would expect it to be as perfect as all the rest. Thanks for a great day and looking to come back in some days for exploring the wreck completely

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!
