MC9 + Compact Regulator

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

The balanced diaphragm MC9 1st stage features Cressi’s PressureSync technology, which maintains consistent Intermediate Pressure (IP) throughout each breathing cycle. This innovative design reduces pressure fluctuations, delivering 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 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 2nd stage is exceptionally compact and lightweight at just 135 gr (without the hose), reducing jaw fatigue on even the longest dives. The large purge is easy to locate and an adjustable Venturi system allows divers to fine-tune airflow – pre-dive mode minimises free-flows at the surface and dive mode optimises performance underwater.

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