Cressi MC9-SC Compact Pro Regulator Introducing the Cressi MC9 Compact Pro Regulator. A truly revolutionary regulator designed to perform in the harshest conditions. Be it that you’re diving in the cold waters of Artic or silty condition waters, you can be assured that there won’t be any freezing or contamination in the air delivery. Covered by a protective techno-polymer elastomer shell, the 1st Stage of MC9 is very light. It is equipped with four low and two high threaded pressure ports, giving you another option to connect your transmitter or gauges. Furthermore, it is coated with anti-friction anti-corrosion material. So, you can be assured that your critical components can move freely with little resistance. Such a feature allows the components to perform and last longer between dives. The first stage regulator is environmentally sealed, and made with chrome plated marine grade brass. The benefit of this design is that none of the delicate internal parts will be exposed to contaminants such as salt, sand, chlorine or pool acids. Thus, greatly increasing the durability of the regulator. This regulator is most ideal for any recreational divers looking to explore the most extreme cold water environments. Weighing at 33.1oz (938g) with hose, it also comes with an Owner’s Manual.
