PADI Master Scuba Diver Trainer Course (MSDT)

The Master Scuba Diver Trainer rating (MSDT) sets you apart from other dive instructors in the eyes of prospective employers. You'll also find it more fun to teach a wider range of courses and open up new experiences for yourself and new underwater worlds for the divers you train.

You'll be able to teach the specialties you love and watch your divers progress from Open Water right up to Master Scuba Diver.  You'll increase your income with multiple level training and by taking the PADI Master Scuba Diver Trainer rating (MSDT) you'll meet one of the requirements to qualify as a PADI Master Instructor. You'll need MSDT too if you plan to become a PADI Staff Instructor, PADI Tec Deep or PADI Trimix Instructor.

Our usual PADI Master Scuba Diver Trainer (MSDT) preparation course consists of these 5 specialty instructor courses:


  • Deep Diver Instructor
  • Wreck Diver Instructor
  • Digital Underwater Photographer (DUP) Instructor
  • Night Diver Instructor
  • Enriched Air (Nitrox) Instructor

However if you have any special requests our Course Director will be as flexible as possible.
