Why do they
call it SCUBA?
SCUBA stands for Self Contained Underwater
Breathing Apparatus
How old do
I have to be to SCUBA dive?
10 years
or older.
How long
can you stay under with those oxygen bottles?
SCUBA tanks do not contain pure oxygen. They are filled
with pure, dry, filtered, compressed air. How long
you can stay underwater is determined by how deep you
will be diving and how hard you are working. The
deeper you go, the less time you have.
Diving can
only be done by good swimmers and people in top physical
condition, right?
You don't
have to be an Olympic swimmer to become a recreational
SCUBA diver but you do have to pass some basic swim
tests.
SCUBA diving is dangerous isn't it?
It's
probably about as dangerous as bowling if you are
trained properly.

Why do my
ears hurt when I go to the bottom of the pool?
As you go deeper under the water, the pressure on your
body increases. Since the pressure on the outside
of your body increases above the pressure in your inner
ear, your ear drum starts to get pushed in and you feel
pain. If you were to continue to dive deeper your
eardrum would eventually burst. Good news!
Its very simple to "equalize" the pressures using
techniques you learn in your 1877 ScubaUSA scuba class
to avoid pain and the possibility of a ruptured eardrum.
Diving should not be painful.
SCUBA diving is expensive, isn't it?
Would you take up skiing and not buy skis? Why
would you get into SCUBA diving and not expect to have
to buy the equipment needed to dive safely? Let's
face it, many dive shops don't maintain their rental
gear as good as they should. Also, rental gear
does not fit as well and is not as comfortable as your
own gear. Studies show that divers that own their
own equipment dive more often and are far more likely to
keep diving. SCUBA diving is an equipment
intensive sport and does require some significant
purchases. Properly maintained, your equipment may
give you many years of enjoyment. Don't just think
about how much you are spending now, think about how
much it will cost you over a period of 5 to 10 years.
Since SCUBA equipment is used for life support,
you should buy the best performing gear you can afford.
Can I dive
with contact lenses? What if I wear glasses?
You should be able to dive while
wearing contacts. If you wear hard contact lenses
you will want the gas permeable type. If you wear
glasses, masks can have lenses bonded to them so you can
see underwater. Read more about
contacts and diving.
How do I properly fit a mask to my face?
A trip to our dive shop in Paramus is your best bet to
ensure that your SCUBA mask fits you properly. The first
step to a proper fitting is to place several different
masks on your face and check that the surrounding seal
fits the contour of your face. Check all around the mask
and under your nose to make sure it fits to your face
without sucking in on the mask. Usually, you will find
several brands and styles that fit, some better than
others. Then, take each mask again and put it on your
face without putting the strap on your head and lightly
suck in through your nose. The mask should seal
completely and stay on your face when you let go of it.
Eliminate any that do not. From the masks that are left,
pick the ones that provide the best field of view.
Finally, choose the mask that you like the best based on
style or preference out of what is left.
How do I properly fit a pair of SCUBA fins?
The fins you select for SCUBA diving will depend on the
type of diving you will be doing. Divers that dive in
warm water, such as the Caribbean, often opt for the
full-foot style of fins. Divers that frequently SCUBA
dive in colder areas like New England usually go for
open back fins with wetsuit boots. To ensure that you
have a properly fitting pair of fins your best bet is to
take a trip to our dive shop in Paramus. If you
will be using open-back fins, bring your wetsuit boots.
If you going to buy full-foot fins and are going to wear
a neoprene sock, bring those with you. Once you get to
the dive shop, you will probably have a number of
different brands and styles of fins to choose from. When
fitting open-back fins you want to be able to slide your
foot up into the foot pocket without it being too tight
or too loose. It should feel comfortable on your foot
with your foot out straight. Don't gauge the fit while
standing up on the fins, your foot will compress and
change the fit! You won't be standing while you are
swimming with them. Full-foot fins should fit snugly but
not too tight. Both types of fins should not be able to
twist on your foot, if they do the fins will rotate and
become less efficient. You may find that several
different brands and styles fit you. If this is the
case, you can choose the fin that fits the type of
diving you will be doing and the color you like. |
