Cressi MC11 SC + Zen Pro Regulator

The Cressi MC11 SC + Zen Pro Regulator is exceptionally lightweight and compact, barely noticeable during long dives. It delivers exceptional breathing performance, even under ice.

The hyper-balanced diaphragm MC11SC 1st stage features Cressi’s Pressure Sync technology, maintaining consistent Intermediate Pressure (IP) throughout each breathing cycle. This innovative design reduces pressure fluctuations, resulting in a smooth and comfortable breathing experience.

The environmentally sealed design ensures the first-stage chamber remains dry, eliminating the risk of freezing and contamination. A high-capacity conical filter with a large surface area traps more impurities from the cylinder, providing cleaner air and reducing maintenance.

The ZEN PRO 2nd stage is purpose-built for cold-water performance, featuring a case made from an innovative Thermoconductive Polymer. This lightweight and durable material offers metal-like heat transfer properties, preventing ice from forming inside the 2nd stage.

Radial pressure openings evenly distribute water pressure across the diaphragm, reducing free-flows and ensuring the 2nd stage delivers air only when needed, even in strong currents.

The MC11 SC ZEN PRO is ready for adventure, from temperate reefs to beneath the ice, with a nickel-plated anti-scratch coating and protective bumpers to guard against knocks and bumps.
