Peter,
Makes you realize some undertanding of the have and the have nots. A little education can go a long way.
These divers are doing up to 15 dives in a day, shallow or not, that is too many. They don't have a depth gauge, watch nor a simple SPG.
My guess is they start to feel the tank go bouyant and then difficulty breathing, then they start their ascent.
In the case of OOG at 130 feet, and bolting to the top instead of drowning, questionable what they are thinking, again having little knowlege of the long term affects of surviving the bends.
They must be aware that it is dangerous because their town is showing crippled divers with similar stories, then why do they do it?
It goes back to the have and have nots, the divers that can continue to make a small bounty will continue while other divers cannot because of disability.
If the supply is there, the poverty diver will risk his life to make the catch.
I feel if they are educated about the dangers in a real classroom setting and given donated equipment, it will bring a safer margin to the liability they are taking.
We have to start somewhere, it's painful to see the diver come out of a chamber ride, and still be in so much pain. You can't help but feel sorry for what they go through.
Peter, I was amazed when in the video the reporter is talking to the guy on the small canoe, the guy who collects the lobsters, she is talking to him about how many they have caught so far, and he explains it's bad luck to count them until the end.
All of a sudden you hear the divers tank start to make a whinning sound on his back, they say, well it's just a faulty tank.
I would not want to be near a compressed cylinder that is making that sound, and he has it strapped to his back, no problem, continues diving it.
They never spoke about hydro's or visuals, I wonder how many or their tanks fail hydros but are still being used for one mans gain and anothers demise?
