Cressi MC11 SC Zen Pro Regulator Yoke

Engineered for Reliable Cold Water Breathing Performance
The Cressi MC11 SC Zen Pro Regulator combines the environmentally sealed MC11 SC first stage with the high performance Zen Pro second stage to create a compact and lightweight cold water scuba regulator. Certified under EN 250 A, this balanced diaphragm scuba regulator is engineered for consistent breathing in demanding conditions. The hyperbalanced diaphragm design increases airflow as cylinder pressure drops, maintaining stable performance throughout the dive. Integrated PressureSync technology helps sustain consistent intermediate pressure during each breathing cycle, reducing pressure fluctuations for smooth and controlled delivery.

Environmentally Sealed First Stage with Clean Air Protection
The environmentally sealed first stage chamber remains dry, helping protect internal components from freezing and contamination in both cold and warm water use. A high capacity conical filter with expanded surface area captures more cylinder impurities compared to standard flat filters, supporting cleaner air flow and reduced servicing frequency. 2 HP ports and 4 MP ports are arranged in a T shape configuration to optimize hose routing while maintaining a compact profile. The first stage features an electroless nickel plated finish for added durability and resistance to wear.

Thermoconductive Second Stage with Controlled Airflow
The Zen Pro second stage is constructed from thermoconductive polymer, a material that transfers heat efficiently to help reduce ice formation inside the second stage during cold water dives. Radial Pressure Openings distribute water pressure evenly across the diaphragm, helping reduce free flows and ensuring air is delivered only when inhaled, even in strong currents. An adjustable Venturi system allows switching between pre dive mode to minimize surface free flows and dive mode to optimize underwater airflow. A simple downstream design provides reliable, fail safe operation, while the large purge button remains easy to locate and operate, even while wearing gloves.
