MC11-SC + Zen Pro + Zen Pro 1St + 2nd Stage + Octopus INT

The Cressi MC11 SC + Zen Pro + Zen Pro Octo is a complete cold-water INT regulator set – compact, lightweight and ready to dive out of the box.

The hyper-balanced diaphragm MC11 SC 1st stage is environmentally sealed, keeping the chamber dry and eliminating the risk of freezing and contamination.

Cressi's PressureSync technology maintains consistent intermediate pressure throughout each breathing cycle, producing one of the smoothest and most comfortable breathing experiences available.

A high-capacity conical filter with a large surface area traps more impurities from the cylinder than a standard filter, ensuring cleaner air and reduced maintenance.

The Zen Pro 2nd stage and Zen Pro Octo are purpose-built for cold-water performance. The cases are made from a lightweight, thermally conductive material with exceptional heat-transfer properties, using warmth from the diver's breath to reduce the risk of ice forming inside the 2nd stage.

Radial pressure openings evenly distribute water pressure across the 2nd stage diaphragm, reducing free-flows when swimming into a strong current. An adjustable Venturi also helps prevent free-flows at the surface, while still allowing the user to maximise airflow in dive mode.

With a nickel-plated anti-scratch coating and protective bumpers to guard against knocks and bumps, the Cressi MC11 SC + Zen Pro + Zen Pro Octo is adventure-ready, from temperate reefs to beneath the ice.

• Cold Water Certified EN 250 A < 10°C
• The Hyperbalanced Diaphragm INT 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
• A simple downstream design 2nd stage and Octo provide dependable performance in a fail-safe design
• Adjustable Venturi maximises airflow in dive mode and prevents free-flows when the regulator is on the surface
• Lightweight (149 gr) yet strong, the thermoconductive 2nd stage case transfers warmth from the water or diver's breath to reduce the risk of freezing
• Radial Pressure Openings prevent free-flows, ensuring the regulator delivers air only when needed, even when swimming against strong currents
