One question we often hear is: What is a master diver? While this phrase may be commonly used to define a skilled, proficient and knowledgeable diver, it isn’t an official PADI certification or rating.
Instead, it is likely used to refer to either a PADI Divemaster or a PADI Master Scuba Diver™.
What Is a Master Diver?
A master diver isn’t an official PADI title, but the person using it may be trying to refer to either a PADI Divemaster or a PADI Master Scuba DiverTM. Both of these elite titles require significant experience and training to achieve.

Divemaster vs. Master Scuba Diver
For a more in-depth look at the differences, take a minute to read this article. Put simply, the difference between a Divemaster and a Master Scuba Diver is the training they have undergone and whether they can work as a dive professional or are a recreational diver. PADI Divemaster is a professional certification, while Master Scuba Diver is the highest recreational rating in the PADI System (earned by only about 2% of divers worldwide).
These differences mean that a Divemaster can perform professional tasks, such as assisting with certain courses and leading dives, while a Master Scuba Diver is recognized for reaching the highest level of recreational dive training by completing their Rescue Diver certification, holding five Specialty Diver certifications and logging 50 dives.
A diver can hold both titles — a Divemaster can also be a Master Scuba Diver, and vice versa.
