Professional diving buoyancy compensator
MK 4
A.P. Valves
The Mk.4 has been designed specifically for surface air and mixed gas diving and is the only commercial BCD of its type to incorporate a full-recovery diving harness, helmet-retaining safety harness and bailout backpack.
The emphasis has been placed heavily on safety and efficiency, allowing the diver greater flexibility underwater without drawing on emergency energy levels.
