Cressi MC9-SC + Compact Pro Regulator

The Cressi MC9 SC Compact Prois a lightweight, compact regulator that combines high flow rates, excellent coldwater performance and reliability all in one system.

The MC9 SC first stage utilises an over balanced diaphragm design for improved performance and also incorporates an environmental seal that prevents cold water and contaminants from interacting with the internal components which helps to prevent ice buildup in extreme low temperatures.

The first stage has a compact inline design that minimises the number of turns the air flow has to make before exiting via the ports. Two high pressure and four low pressure ports provide ample options for hose configurations and allows both a pressure gauge and wireless transmitter to be fitted at the same time.

The Compact Pro second stage is made from a combination of lightweight ABS and elastomer materials and stainless steel components to ensure it is light and compact. Its combination of performance, reliability, weight, price and cost of maintenance make it a perfect travel regulator.

The Pro version incorporates particles in the second stage body that help improve the thermal conductivity and to prevent freezing in cold environments.

The Compact Profeatures a purge button that is between 80-400% larger than that of any other regulator on the market to facilitate purging, especially for beginning divers.
