PRoDuct oVERVIEW
This buoyancy jacket is specifically designed for military use with all types of back or chest worn breath-
ing apparatus, including open circuit SCUBA, semi-closed circuit or closed circuit rebreathers.
The MDB features a single air cylinder attachment that allows you to inflate the vest with
compressed breathing air. The air cylinder is equipped with a Groupe d' Etudes et de Re-
cherches Sous-Marines (GERS M20) 90 degree connection for use on the jacket. The
breathable inflator allows you to breathe from the bladder in an emergency situation.
The distribution of the buoyancy chambers provides excellent safety performance, either during
buoyant ascent (vertical stability) or at the surface (natural support position with head and shoulders
out of the water). The bladder is constructed of heavy duty urethane coated 1000 denier black
material which resists cuts, tears and abrasion and is impervious to sunlight and salt water. Two
drains with tethered caps on the bottom side makes draining fast and easy.
The bag is sewn throughout with high strength nylon. A crotch harness with split strap design pro-
vides greater comfort while maintaining ease of adjustment. In addition, it has two utility pockets
on the left lobe.
The MDB is suitable for all types of uses.

Bc Air Breathing
The oral inflator is equipped with a breathing valve that allows the diver to breathe air from the
buoyancy compensator when inflated. This device is only to be used in case of an emergency.
To breathe air from your BC, first slightly exhale through the oral inflator mouthpiece in order to
remove excess water trapped in the mouthpiece's body (Fig. 1). Then, inhale through the mouth-
piece. This will activate the breathing valve and deliver air from the BC's bladder. When done
inhaling, exhale through the mouthpiece. The breathing valve permits both inhaling and exhaling
without any manipulation.

WARNING: Always keep in mind that breathing air from the BC also deflates the BC
and changes your buoyancy. Always be prepared to add air in the Bc from the emer-
gency cylinder in order to get extra air to breathe and also extra buoyancy.
Depending on the depth, the auxiliary cylinder will only provide a few minutes of air, so you must immedi-
ately start a controlled ascent to the surface.
cAutIoN: the inside of the bladder must be kept dry and clean of all contaminants.
If not maintained properly, breathing from the Bc in the case of an emergency could
cause suffocation or asphyxiation due to contamination.
