Uniquely tailored for surface supply diving with air and mixed gas, this state-of-the-art commercial buoyancy control device (BCD) stands as the industry's only solution that incorporates a full recovery diving harness, helmet-retaining safety harness, and bailout backpack.

Safety and efficiency take centre stage in the Mark IV's design, providing divers with unparalleled flexibility underwater without compromising energy levels. By offering complete buoyancy control and diver mobility, this innovative BCD empowers divers to achieve neutral buoyancy, slight positive buoyancy, or slight negative buoyancy, facilitating seamless navigation to the work-site from the diving bell.

With the Mark IV's neutral buoyancy capability, divers can now swim or "jump" to the next work-site without necessitating bell movement. This groundbreaking feature ensures:

• Total buoyancy control, comfort, and diver mobility
• Direct approach to the work-site
• Enhanced freedom of movement at the site
• Significant savings in work-time

Key Features of the Jump Jacket Mark IV include:

• Primary buoyancy-gas supply via a Swagelok quick-fit 'cross-connect' hose from the helmet side-block.
• Secondary pneumo buoyancy-gas supply.
• Tertiary buoyancy-gas supply from twin-cylinder bail-out supply.
• Integral diving harness with front and back lifting points for diver recovery and facilitating resuscitation.

Furthermore, the Mark IV brings significant dive safety improvements, enabling faster rescue approaches, gas donation to distressed divers in case of compromised umbilical supply, and swift return to the bell through buoyancy control for both rescuer and patient. The integrated lifting harness ensures rapid patient recovery into the bell.
