There are many famous diving areas in Thailand, but none hold a candle to the southwest Andaman Coast. Only this area in Thailand offers world class diving. Other areas may be good for learning to dive, but if you want a serious dive holiday, your destination should be Phuket or Phang Nga provinces. Liveaboard diving is the most comfortable way to dive here and often the only way to reach our remote destinations.

The owners, John Williams and Bent Posejpal have been leaders in the diving scene around southern Thailand since the late 1980s. John Williams has authored or contributed to four popular dive guides on Thailand and Mergui. Bent Posejpal has been a PADI Course Director since 1994 and has trained hundreds of PADI instructors. They have trained thousands of students and led thousands of dives. Both were among the first to discover, explore and share with the world many of the now famous dive sites in the Andaman Sea. Both are professionals who have made Phuket their home and scuba diving their passion.

We believe that selling dive travel takes not only a special dedication but a particular knowledge. Our aim is to find you the right vessel and destination. Before making personal recommendations, we consider your diving experience, dive travel history, level of comfort expected and length of time available, all wrapped up inside a price you can afford. We have the experience to do just that.
