Hello! I figured here was a good place to drop this:
So I know (I think) free diving is deep water diving, maybe with fins and snorkel, and involves plenty of breath holds/distance swims.
My questions: What are the tests like? Is free diving easy to learn (I know there are classes)? Roughly how long do you train...or is it something you constantly work on? Do classes teach you how to handle aggressive fish?
Thanks (I apologize for any obvious questions)
