Khao Lak Scuba Adventures PADI 5 star CDC Centre offers two types of PADI divemaster packages. A 4 week course and an 8 week course. Both courses cover everything you need to know to become a professional divemaster. Each course offers you the chance to make 3 trips on any one of our 7 boats ranging between 3-5 days in length. You will be training with mainly Jack and Patricia, but also at times with instructors on the boats as well which will expose you to vast amounts of knowledge that is invaluable at the start of your professional diving career.
