The MC9-SC Compact Pro hyper-balanced diaphragm 1st stage regulator has a lightweight body covered by protective techno polymer elastomer shell. The regulator has 4-low pressure & 2-high pressure ports. Internally the 1st stage is coated w/an anti-friction anti-corrosion material that reduces resistance & allows components to move freely. This makes the 1st stage perform & last longer & increases performance. The chrome plated marine brass 1st stage is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for surrounding water to enter the intricate mechanism. The 1st stage MC9 - SC has a special seal chamber (SC) which completely isolates the diaphragm and spring from contact with water. Ideal for diving in waters that are rich in suspension and mineral salts, for archaeological work, for potholing and diving in cold waters.
