Cressi MC11-SC Zen Pro Yoke Regulator

1. Effortless Breathing

The Cressi Zen Pro regulator is engineered to deliver exceptionally smooth, natural breathing at every stage of your dive. By reducing breathing resistance and optimizing airflow delivery, it allows you to conserve energy and stay relaxed underwater.

Whether you're descending, cruising at depth, or making your safety stop, the Zen maintains consistent performance so you can focus on the experience—not your gear.

2. PressureSync Technology

At the core of the Zen regulator is advanced PressureSync Technology, designed to maintain stable intermediate pressure regardless of depth or tank pressure. This balanced system ensures that airflow remains consistent and predictable throughout your dive, eliminating fluctuations that can disrupt breathing comfort. The result is a regulator that adapts seamlessly to changing conditions while delivering reliable, high-performance air delivery when you need it most.

4. Intelligent 2nd Stage Design

Comfort meets performance with the Zen’s intelligently engineered second stage. Designed to fit naturally and reduce jaw fatigue over long dives, it offers an ergonomic profile paired with optimized airflow geometry. This thoughtful design enhances breathing ease while giving divers better control and a more intuitive feel, making it ideal for both newer divers and seasoned pros alike.

6. Built for Real Diving

The Zen regulator isn’t just designed in theory—it’s built for real-world diving. Constructed with durable, high-quality materials and backed by Cressi’s long-standing reputation for reliability, it stands up to frequent use in a variety of environments. From local dive sites to travel destinations, the Zen is a dependable companion for divers who expect performance, durability, and consistency every time they hit the water.

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.
