PRE-DIVE
BCD EXAMINATION
The pre-dive, dive, and post-dive BCD examinations help identify
equipment problems before unsafe conditions exist. Equipment-
related diving accidents can be prevented by following these sim-
ple steps and having all equipment regularly inspected by an
authorized scuba equipment repair facility.
VISUAL INSPECTION
Examine the entire BCD for cuts, punctures, frayed seams.
Excessive abrasion or other damage. If there is any doubt of the
condition of the BCD, do not dive.
Inspect the OIDV/PIV Assembly for any cracks or damage. Check
the OIDV Button and OIDV mouthpiece for sand or other debris.
Check the EDV (2) EXHAUST DUMP VALVE and the OPIV (7)
housings to make sure they are free from damage, sand and or
other debris.
OPERATIONAL INSPECTION
After the visual examination, it is recommended to test the BCD's
operating systems.
Test the oral inflator by inflating the BCD through the oral inflator
mouthpiece(1). Check the inflation system and the BCD for leaks.
Let the BCD stand inflated for 30 minutes or more. Check the
BCD for any loss of air.
Test the power inflator by attaching the male quick connect (4) to
the pressurized L.P. hose (6) and depressing the power inflator
button (3). Check the inflation system and the BCD for leaks. Let
the BCD stand inflated for 30 minutes or more. Check the BCD
for loss of air. Allow the BCD to remain connected to the pressur-
ized L.P. hose. Deflate the BCD using the deflator button (2) and
allow to stand uninflated for 30 minutes or more. Leakage through
the power inflator (3) will be evident if the BCD self inflates.
Test the dump valve by pulling on the inflator assembly. The
internal cable will activate the upper dump valve (7). The valve
should close properly upon release.

CONSTRUCTION and MATERIALS
Your BCD may employ either a single bag or double bag construc-
tion. The double bag BCD is constructed of a strong nylon fabric
outer shell and a durable polyurethane inner bladder. The urethane
bladder is radio frequency (RF) welded to provide a durable air
chamber. The single bag BCD is constructed of a single chamber
made from a 420 denier nylon fabric backed by a polyurethane
coating. This high strength fabric composite provides exceptional
resistance to tears, abrasions, and punctures. The single bag is
also RF welded to provide an exceptionally strong seal. All hard-
ware and related items on your BCD such as buckles, D-rings, and
webbing have been chosen for their superior strength and resist-
ance to the harsh conditions the diving environment places upon
them. With proper care, your BCD will provide years of service.
SCUBA CYLINDER MOUNTING PROCEDURE
Refer to the following diagrams to properly assemble the tank
strap.
1. Soak the mounting bands in water. Nylon expands as it
absorbs water. Soaking will permit the natural stretch of the
nylon webbing.
2. Place the SCUBA tank against the mounting plate on the back
of the BCD. Pull the end of the tankband around the tank.
3. Make sure that the buckle is in the "open" position.
4. Thread the end of the band between the metal ring and the
plastic body of the buckle.
5. Feed the end of the band through the center slot on the top side
of the buckle.
