Master Scuba Diver course is the highest rank you can achieve before turning Pro.
To complete this you must be over 15 and have completed OWD, AOWD , Rescue Diver and five Speciality certificates. You must also have over 50 logged dives. The certificate denotes high skills, top achievement and broad experience.
The Master Scuba Diver rating places you in an elite group of respected divers who have earned this rating through both significant experience and scuba training. Fewer than two percent of divers ever achieve this rating. When you flash your Master Scuba Diver card, people know that you’ve spent time underwater in a variety of environments and had your share of dive adventures.
Every diver, who is at least 12 years old, should aim for Master Scuba Diver.
The path starts with earning a PADI Open Water Diver certification, followed by PADI Advanced Open Water Diver and PADI Rescue Diver (or qualifying certifications). You also need to earn five PADI Specialty Diver certifications and have logged a minimum of 50 dives.
