Specialty courses allow you to deepen your knowledge and techniques
You will become a "specialist" in your chosen field, thanks to:
your personal work
a theoretical course from your instructor
and sea dives
The courses last between 1 to 3 days depending on the specialties chosen.
By accumulating 5 Specialty certifications, you can obtain the highest level of recreational diving: the Master Scuba Diver.
Note : the dives made during your Advanced Open Water count as the first dive of each specialty.
