Frequently Asked Questions


Is it safe to learn to freedive online?
Absolutely it is safe. We believe that safe diving comes through access to knowledge. An online course cannot replace training with an instructor however and we recommend that you take a course or arrange some training with a qualified freediving instructor.
Does this course replace training with a freediving instructor?
No. This course is designed as continued education or a refresher for those who have already trained with a freediving instructor. It is also designed to provide further insight into freediving skills for certified freedivers.
Does this course give me a Freediving Certification?
No. While this course does contain all the equalisation information from a Level 3 and 4 course. This digital course is not a recognised freediving course with any of the current freediving agencies.
Does this course contain all the information I would encounter in a certified freediving course?
Yes. In this course I teach everything that I would teach in one of my freediving courses and much more!
