Cressi MC9 Compact INT Scuba Dive Regulator

Ideal scuba diving regulator for beginners and travelers. Hyperbalanced membrane 1st stage plus a compact single-hull second stage. 2 HP and 4 LP ports. Weight: 878 g - 31 oz. Very light and made in Italy.
The hyper compensation of the 1st stage mechanism guarantees a slight increase of the IP as it gets down the pressure of the bottle. The regulator supplies, therefore, its maximum level of services in the final phase of the dip, undoubtedly the most critical. The chamber is designed to canalize the air volume directly to the  LP exits for reducing to minimal level the fall of pressure in forced breathing (0.5 BAR), guaranteeing a use with high services in any situation. The thicknesses of the walls of the body have been optimized to reduce to the minimum its weight. A case of semiflexible elastomer protects the 1st stage of blows and erosions. Seat HP of stainless steel AISI316. Apart from the possibility of substitution in case of deterioration on having realized the maintenance, the composition of the seat, much harder than the traditional brass of the fixed seats, it prolongs its useful life since it resists better the deforming action of the metallic microparticles than could introduce proceeding from the bottle.
Greatly simplified single-hull 2nd stage made of ABS + elastomer of really compact size and extremely light.  Its mechanism and development are perfectly planned to obtain the minimum number of components and great strength. It's a smart shopping option because of its combination of features - reliability - price - maintenance cost. Asymmetrical frontal 2nd stage cover drilling. The water flow pushes the diaphragm anti-clockwise direction to create its retraction in a flat position and to make the lever decrease gradually in precise perpendicularity, regardless of condition. The specific calibration of the inhalation mechanism changes slightly the personality on air output according to Ellipse series, rewarding an abundant flow without the need to exploit Venturi effect, beyond the exquisite touch and sensitivity of these kinds of regulators. This feature provides a limited tendency to continuous flow on the surface or during the placement of equipment into the water, excellent for schools and renting (both the octopus and the double regulator). However, the results of the features place it beyond regulators of the highest range.
The MC9/Compact regulator is designed and manufactured in Italy by Cressi, an Italian brand pioneer in scuba diving, snorkeling and swimming equipment since 1946. The product is covered by a 2-year limited warranty.
