Dive
Equipment
By this point you realize you need equipment
to dive. You may be well on your way
to owning a complete set. So. you're
probably already familiar with basic
types of dive equipment. But you may
not be as familiar with some of the
specific features or options that apply
to each type, or what separates equipment
aimed primarily at snorkeling from equipment
intended for scuba diving. Also, you
may not yet be aware of some equipment
you'll use.
This
subsection looks at equipment basics
for masks, snorkels, fins, BCDs, scuba
tanks, regulators and submersible pressure
gauges, each of which you'll use during
your confined water dives.While you'll
learn the basics here, keep in mind
that dive gear comes in myriad styles
and col-ors that makes it comfortable
and stylish as well as functional. What
types work best for you will depend
on your preferences, the type of dive
activities that interest you, where
you'll be diving and other variables.
Your PADI Dive Center, Resort or Instructor
can show you the different types and
models that best suit your needs.
Masks
Patrpose,
It's not earth-shattering news that
you need a mask to see underwater. Why
you need it is that light behaves differently
in water than in air, and your eyes
focus accord ing to how light behaves
in air. That's why water makes everything
blurry. The mask creates an air space
so your eyes can focus.
When
buying a mask, don't skimp. Get a good
one specifically designed for scuba
diving that fits you properly. If you
think about it, in warm As you learned,
the mask creates an air space you must
equalize during descent to prevent mask
squeeze. That's why the mask must enclose
your nose. Goggles, which cover only
the eyes without enclosing your nose
can't be equalized. They're fine for
surface swimming, but they're not acceptable
for diving.
