MC9 SC + Compact Pro Regulator

The MC9 SC + COMPACT PRO combines innovative materials with a compact and ultra-lightweight design.

The balanced diaphragm MC9 SC 1st stage features Cressi’s PressureSync technology, which maintains consistent Intermediate Pressure (IP) throughout each breathing cycle. This innovative design reduces pressure fluctuations in the 1st stage, delivering one of the smoothest and most comfortable breathing experiences available.

The environmentally sealed chamber keeps water and debris away from the internal components, protecting lubricants and ensuring reliable performance in cold and warm water conditions.

A high-capacity conical filter with a large surface area traps more impurities from the cylinder than traditional flat filters. This improves air quality and protects the regulator from damage caused by debris entering the 1st stage – an essential feature for travelling divers using rented cylinders.

The COMPACT PRO 2nd stage case is made from a Thermoconductive Polymer. This innovative lightweight material transfers warmth from the surrounding water or the diver’s breath to the internal components, preventing ice from forming inside the 2nd stage. The adjustable Venturi system allows divers to fine-tune airflow, reducing free-flows at the surface and optimising performance during dives.

With its elastomer bumpers, anti-scratch nickel-plated coating and impact-resistant front cover, the MC9 SC + COMPACT PRO is built to last.
