Scuba Diving for Beginners : Tips for Using Scuba Diving Regulator

You don´t measure the amount of air in PSI. A tank can't hold "3000 PSI of air". You measure the amount of air in liters. So the amount of air a tank holds can be expressed in liters @ a given PSI.

this little red zone isnt you out of air, like the gas light on your car, look hey you might wanna come up but dont have to right away, wtf....? You should use that line as you are out of air at that point and when it hits 50bar you want to be on the surface. or atleast asending not thinknig i have 3-10 minutes of air.

Ya, well they teach both in us schools but the problem is that the parents and culture use the imperial system which makes it easier for Americans to visualize when you throw numbers around. (like 5 inches or half a mile)

At least we use it in science and track and field. It really does simplify things

Is it just me or does the US DIVER logo on that REG look like something else when upside down????

Oh yea, I know the PSI system here in the US very well, but I really like the metric system better as far as BAR..

".. and, eh .. in REST OF THE WORLD.. they messaure in bar" .. Says something about the power of things like metric and similar. We rule it, now change yours so all the world has the same form.
