For beginner courses, you should bring a swimsuit, towel and a container of water, as hydration is extremely important, especially during the summer. Equipment rental is included in the price of the course in these cases. For courses that follow the beginner ones, it is recommended that participants who have already gained some knowledge of equipment also purchase some of their own equipment. Regardless, all recreational courses include equipment rental.
However, this does not apply to courses for obtaining professional categories such as PADI Divemaster, PADI Assistant Instructor and PADI Instructor (various types of instructor categories).
