And I’m a high school dropout
When I first started going into the dive shop to gather skin diving gear so I could go abalone diving, I asked if they offered any sort of abalone diving or freediving class and they replied they did not. But because I asked, the manager decided to start one just for people like me. I can’t remember the cost, and it was not affiliated with PADI, there was no card, it was just a seminar through the store. They came up with a curriculum that included an evening of some class time going over freediving physiology and some pool practice. A pretty good group signed up. The very next weekend we went to the ocean and put our skills to work. I even got a couple nice abalone!
Taking that class was worth every penny. I could have just started like everyone else, a hack just trying to figure it out on my own and maybe from buddies who were hacks too, but I went on that first ab dive with some professional advice from accomplished freedivers and it really helped.
