Well it seems a few people enjoy/do this.
So why not share stories?
I for on love it, As a sport and a Job, I've been diving no end of times, For both work and recreational.
I got myself a certification with
NAUI, I got my lessons done for free because my father had worked for the guy before.
Im the third generation of divers in my Family, My Grandfather was a
BSAC Instructor and Dive Master, And then he ran his own SCUBA school/club with
BSAC. My Father works in diving for a career, He has I think around $20,000 worth of gear (Kirby Morgan stuff :P), He has around 12-15 Qualifications such as Rescue Diver, Advanced Diver, Dive Master, and one I think is an instructor one. Most with
PADI (Who if you know me I/My Family hate). I was brought into it when I was 11, And recently as I said got certified, unfortunately I only have a Jr card, But I will be renewing it when I am 16.
Feel free to share stories/questions we can answer

(For reference I have added links to the Organisations incase anyone is interested)
