The compact and lightweight Cressi Zen Octo delivers the same comfortable breathing experience as the Zen 2nd stage, but in high-visibility yellow for quick identification in emergencies. Designed for use in water temperatures above 10°C, the Zen Octo features an adjustable Venturi, which helps reduce free-flows at the surface and underwater. Radial pressure openings evenly distribute water pressure across the diaphragm, further minimising the risk of free-flows, even in strong currents. The large purge button is easy to locate and operate when needed. Built with a fail-safe downstream design, the Zen Octo continues to deliver air even in the event of a malfunction, providing a reliable backup air source when it matters most.

Highlights :

• Warm Water Certified
• EN 250 A > 10°C
• A simple and dependable downstream system offers reliable performance and a fail-safe design.
• Large purge button is easy to locate and use in an emergency.

The Cressi T10 SC PVD Master is designed for divers who expect high levels of performance in demanding conditions. The T10-SC PVD 1st stage has a hyper-balanced diaphragm that adjusts airflow to match ambient water pressure for improved breathing performance at depth, even as cylinder pressure decreases. The environmentally sealed design keeps water and debris out to prevent the risk of freezing or contamination. A conical 1st stage filter offers a large surface area for the efficient filtration of impurities from the cylinder. The conical shape means that the filter can handle more contaminants before needing to be replaced. This high-performing 1st stage is finished in a super-tough PVD titanium coating that will keep your regulator looking good for years. The Master 2nd stage features a premium laser-etched titanium front cover and the elliptical design fits naturally against the diver’s face. The elliptical diaphragm has a large surface area, which reduces the effort needed to inhale, especially in high-demand situations or at depth. Cold water performance is further improved by the Master’s internal heat exchanger, which uses warmth from the diver’s breath, or the surrounding water, to stop ice from forming inside the regulator. A large breathing effort adjuster lets divers easily customise airflow, even when wearing gloves. The MASTER uses our Safe-Flex hose, which is incredibly flexible compared with traditional hoses.

Highlights :

• Cold Water Certified EN 250 A < 10°C
• The Hyperbalanced Diaphragm 1st stage increases airflow as cylinder pressure drops, for a consistent breathing experience at all depths.
• Environmentally sealed for cold/warm water diving - the 1st stage chamber stays dry, protecting the internal parts from freezing or contamination.
• 2 7/16” HP ports UNF
• 4 3/8” MP ports UNF
• The ports are arranged in a T-shape to optimise hose routing and minimise the space required.
• With minimal inhalation effort, the T10 SC delivers a smooth, natural breathing experience and outperforms most regulators on the market.
• Special PVD coating and titanium front cover are highly resistant to scratches, corrosion and wear.
• Advanced pneumatically balanced 2nd stage reduces breathing effort at any depth, for an exceptionally smooth breathe during demanding dives.
• Adjustable venturi maximises airflow in dive mode and prevents free-flows when the regulator is on the surface.
• Adjustable venturi maximises airflow in dive mode and prevents free-flows when the regulator is on the surface.
• Patented elliptical diaphragm increases diaphragm surface area for a smoother and more responsive breathe, without added bulk.
