Whether it's ignorance, laziness or just a cavalier attitude is hard to tell, but an inordinate number of gas emergencies are caused by hose failures failures at points that show tell-tale signs of long-term deterioration, and that could have been prevented by a rudimentary inspection and annual service. The classic hot spot is around hose crimps - look for deformed outer hose casings and move or remove hose protectors that cover crimps to get a good view. As you can see in Table 1 a LP hose...

It is somewhat variable and may be used to gauge how far you can swim from a dive's exit point at depth before it's time to turn around and head back. It's a useful...

Diver Has 3400 Litres Of Gas In A

If solo diver B starts out with a partial fill that gives him a starting volume of a little more than 95 cubic feet, his allowable usable volume will be about 64 cubic feet. Since he is using 3.42 cubic feet of gas every minute, his dive can only last for about 18 minutes before he violates the Rule of Thirds. SAC is a constant and represents gas used at rest on surface. RMV is a variable and represents gas needed for specific dive. For many divers in a buddy diving situation, the sort of basic...
