One important scuba diving equipment is
the buoyancy compensator device which will help you to adjust buoyancy
when you ascend and descend. Without the BCD you will either be constantly finning to prevent
yourself from sinking or involuntarily float to the surface with
possible problems. The reason that you can remain neutrally buoyant
in the water is because BCDs continuously add or remove air from
the air bladder. BCD, known as adjustable buoyancy life jackets or stab jackets,
are a multi-component system to which the scuba cylinder, regulator,
alternative air supply, accessories and weights are attached whereby
the whole system can be put on or remove as a single unit. Wings,
also known as the back-mounted inflation BCD, is usually used by
underwater photographers. Most BCDs have a low pressure 'direct-feed'
or 'power-inflator' connected to the regulator for easy inflation.
Should you over inflate the bladder, you will be glad to know
that all BCDs have over pressure release valves. You must always
make sure that your BCD is dry before packing it away. |
