Scuba Diving for Beginners : Tips for Using Scuba Diving Regulator

Scuba Diving for Beginners : Tips for Using Scuba Diving Regulator

Hi this is Cole with Expert Village and I’m
going to be going a little more in depth with the regulator. Now there are also the submersible
pressure gauges, the air gauge here in the U.S. measured is pounds per square inch or
PSI and in the rest of the world it measures it in Bar. A full tank, typically a full eighty
cubic foot tank holds about three thousand PSI of air. This little red zone right here
is not like, you’re out of air, it’s just a caution zone, it’s kind of like the gas
light on your car, letting you know, hey you might want to think about starting to come
up but you don’t have to right away. Depending on the depth you’re at you could have anywhere
from three to ten minutes of air, roughly. The depth gauge up here monitors the pressure
of the water and determines the depth. Most depth gauges also have a little needle that
you can turn to mark your maximum depth of that dive so you can calculate how much nitrogen
you absorb and things like that. Even though the depth gauge goes up to two hundred feet
the recreational diver limit with deep diver training, at least with PADI, is one hundred
thirty feet. Some regulator set-ups also include computers where they’re integrated or not
integrated. Basically what integrated means is that it would be attached here and instead
of an air gauge, the computer would monitor how much air. Most people or a lot of people
have these but they can fail every now and then, so you need to have a back up system
usually just in case. So a lot of people prefer the non integrated computer because then you
have your analog air gauge which rarely ever fails and then your computer which can calculate
how much nitrogen you absorb and how long you can stay down based upon the depths you
are at, pretty easy to operate. Most of them have a log, which you can go back through
and look at past dives.

  1. 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..

  2. 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

  3. 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.

  4. 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.
