I ran into an urchin diver once at a local dive shop in my area. He brought in a wetsuit that he had made and there was some discussion about the quality of it.
Anyway, I got to talking to the guy at length and found out a ton about commercial urchin diving. He had been at it for years. This guy was a block, rugged and gnarled, you could just tell he was tough as nails and salty as hell, super nice guy though.
It turns out he was not certified for recreational scuba and mentioned that he couldn’t get on a recreational dive boat or get an air fill. The owner was standing right there behind the counter and just kind of agreed with him then said “We’ll, we can fix that for you”.
It was interesting how seasoned this guy was but yet just because he was lacking a card how handicapped he was to just enjoy recreational scuba.
He mentioned he wanted to retire from urchin diving soon and wanted to do some fun dives in Hawaii.
So here this guy who has more dives than god has to sit through a class taught by some instructor with probably one tenth of his experience and pay the $400 or whatever just so he can go to Hawaii.
Ironic.
