Those were mostly horse collars "BC" back then, not anything like we have now. The first types didn't even have auto inflators, just 1 or 2 CO2 cartridges and an oral inflator.
Right off the bat you're comparing air diving/decompression to other than air decompression. Deep stops with increased O2 is much different than air. I would say if more Navy divers got DCS on deep stops with air, then it is more likely the deep stops and not the divers. IMO. Air...
Here in RI if a diver gets caught coming out of the water with a piece of a lobster he/she will be charged with a crime. That's the way it should be. Some people will take just the claws of a short lobster thinking they can beat the size limit. Knowing the laws where you are diving is an...
I've heard of that but have never seen it, they must think that people that buy Acuras just call tow trucks when they have a flat!
I guess if ya think to ask the salesman about the spare tire and he shows you a can of flat fix, it could be a deal breaker. But who asks about the spare tire when...
In the USA we have fake spare tires that can't be driven over 50MPH when used, so we rotate the 4 tires on the car. My Subaru's tires get rotated from front to rear every 7K miles. Unknown to most people because the spare is a smaller diameter than real tires when using the doughnut type fake...
99% of the time I am walking into the water not jumping. Often I set my kit up at home and drive to the dive site with the air off.
Although I have jumped into the water with my air off that is not a reason to panic. With an inflated BCD the diver will be bobbing up in a few seconds. What is...
How about green? Green was the current color. a change to yellow was suggested.
Personally I don't rely on colors, I use feel. I can tell one 2nd stage from the other by the differences in the way they feel.
My primary 2nd has a slotted adjusting knob, my octo has a knurled adjusting knob...
Most everyone we dive with do not do primary donate with octo necklaced. I do not donate my primary that stays in my mouth so that leaves me donating my octo on a 40" hose.
Personally I prefer the old school buddy breathing. It keeps both divers in close contact and IMO that proximity can be...
