Master Scuba Diver Trainer (MSDT)

MSDT is the ultimate recreational dive instructor rating. This pro level sets you apart from the pack since it speaks to your experience and commitment to teaching a variety of courses. Because of this, many employers look for the MSDT rating when searching for new team members.

Becoming an MSDT

All PADI Instructors who have certified at least 25 PADI Divers and have earned five or more PADI Specialty Instructor certifications can be a Master Scuba Diver Trainer.


Pura Vida Divers offers an MSDT Prep course that provides you with the 5 instructor specialty certifications needed to become an MSDT. Students often choose to complete this course as part of our Resort Operations Program (Dive Professional Career Level 3). The Resort Operations program packages MSDT Prep with other instructor courses that will make you a vital member of any dive shop.

We also offer the option to complete MSDT prep or any of our instructor specialties a-la-carte. For more information on taking stand-alone courses, contact us at
