The Cressi MC9/Compact Regulator is an 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 the tank pressure drops (which makes it easier to breathe). 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 a 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 weight.
A case of semiflexible elastomer protects the 1st stage against blows and erosion. The composition of the seat is much harder than the traditional brass seat, which prolongs its life. 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.
