OPERATING INSTRUCTIONS Equip to quick-access toolbelt. Trigger to shoot to the surface.
Use alternate trigger to inhale 15 seconds of oxygen.
BACKGROUND The reusable air bladder is a self-rescue and mobility tool for shallow water divers.
—Internal pump (the same unit used by the All Environment Respiration tank) stores pressurized air —Trigger the unit to release air into bladders, inflating them to full buoyancy —Maintain a tight grip while the bladder lifts you to the surface
If the diver strikes an obstacle (such as a cave roof) the unit will automatically halt its ascent to avoid trapping the diver.
Bite down on the relief valve to inhale stored air, providing around fifteen seconds of extended consciousness.
If you experience sharp joint pains after ascending with the air bladder, you are suffering barotrauma ("the bends"). Your AEP suit should correct this issue automatically. If pain continues, consult a medical specialist or a biobed for treatment options.
