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. True featherweight compact 2nd-stage housing is made of durable non-corrosive hi-tech polymers & has a downstream demand valve mechanism. The flow of air is channeled to the mouthpiece by injection, creating a venturi effect enhancing the performance. The 2nd stage comes w/a flow deviator that acts on the Venturi effect, w/dive/pre-dive adjustment function. Large soft purge cover allows easy clearing of 2nd stage & a comfortable silicone mouthpiece. The Compact MC9-SC weighs Regulator weighs 33.26oz (943g) w/hose.
