DeFLAtioN MethoDS
To deflate the BC using the oral inflator,
lift the inflator body to its highest possible
position (above the head). Press the oral
inflator button
(a)
to start venting air. This
method is most effective on the surface
when starting the initial descent.
Throughout the course of a dive, it will be necessary to release air from the
BC using one of the three methods described in the following instructions.
Each method uses a valve that is in a different location. The method you
choose at any time may depend on whether you are making your initial
descent feet first, headfirst, or maintaining neutral buoyancy underwater.
Always remember to utilize the valve that is at the highest point on the
bladder, depending on your position in the water.
Deflation Via the Oral Inflator
Inside the power inflator’s hose is a cable that
attaches the lower power inflator assembly to
the Rapid Exhaust Valve (REV) at the top of
the airway assembly. You can vent air from
the BC by firmly pulling straight down on the
lower power inflator assembly. Once resistance
is felt, only 1/4" of pull is needed to open the
REV (Excessive force is not needed). The REV
provides an effective and convenient way to
vent air from the BC while in either an upright or
facedown swimming position.
