Additional specifications
- 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 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.
- 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 while keeping the first stage compact.
- Cressi’s PressureSync technology maintains Intermediate Pressure during the breathing cycle for a consistent breathing experience.
- Adjustable venturi maximises airflow in dive mode and prevents free-flows when the regulator is on the surface.
- Radial Pressure Openings prevent free-flows, ensuring the regulator delivers air only when needed, even when swimming against strong currents.
- Large purge button is easy to locate and use, particularly while wearing gloves.
