who knows what his secret is....it's possible that old, out of shape, beer swilling, DIR reject is a retired USN Master Chief diver who's been diving for 40+ years and thousands of dives....he's probably still living on the edge like he's always done and plans on checking out the same way...biggest thing he's worrying about underwater is trying to remember where he put his car keys
would I suggest anybody dive the same way?...nope
would I have taken the time to ask him for some advice?..you betcha
you may not approve of his technique or his methods or even have to accept his advice, but it's just possible that he may of imparted a nugget of wisdom that would be priceless to you
There are no "Master Chief divers", there are "Master Chief, Master Diver", then a trade such as "Chief Electricians Mate" A large Naval base might have 2 or 3. Think of them as the Command Sarget Majors of the Navy Divers.
If you ever meet one who is on active duty and has just past his diving physical, every 6 months, you have met one of the best in shape 40 to 45 year olds you ever will.
As for streaching the tank - skip breathing, breathing shallow, and a bit of Zen will take you a long way.
