Purchase.
Virtually every
BCD on the market
has these features,
so besides fit and
comfort, you'll
buy your BCD based
on other features.
Try to choose a
BCD that's as streamlined
as possible. Other
desirable features
include a utility
pocket, a whistle
for surface communication,
hose retainers and
utility rings for
attaching accessory
equipment. Many
divers like BCDs
that include a weight
system, which eliminates
a separate weight
belt (more about
weight systems in
Section 2). Your
dive center, resort
or instructor can
help you find an
appropriate one.
Materils. Modern
BCDs come in either
doublebladder (or
"bag")
or single-bladder
designs. The single-bladder
design is usually
ma-de from a coated
fabric that serves
to both hold air
and resist cuts,
punctures and abrasions.
Doublebladder BCDs
consist of an inner
bladder (usually
made of urethane
plastic), which
holds the air, and
an outer nylon shell
that protects the
inner bladder from
cuts, punctures
and abrasions. Single
bladder types have
become the most
common.
Prepation
For Use. BCDs require
adjustment for a
proper fit. If it's
too loose, it rotates
awkwardly around
you, and if it's
too tight, it can
restrict breathing,
especially when
you inflate it.
Fortunately, most
modern BCDs adjust
easily - you can
usually tighten
or loosen them (to
a degree) without
taking them off.
With
the BCD deflated,
estimate the adjustment
of the straps, lengthening
or shortening them
as needed. Next,
put it on (have
someone help you
if necessary) and
fine-tune the adjustments
until it fits snugly,
yet comfortably.
Finally, inflate
the BCD. Even fully
inflated, it shouldn't
feel restrictive.
Your instructor
will help you adjust
your BCD during
your confined water
dives.
