New ultra-simplified ABS + elastomer monocoque 2nd stage, very small in size (6 cm diameter), very light (145 g) with a mechanism and construction designed to obtain the minimum number of components and great robustness. It is an intelligent purchase option due to its combination of performance-reliability-price-cost of maintenance, ideal for uses that require maximum reliability and also as a travel regulator given its lightness combined with the MC5 1st stage, for diving centres or as a work regulator with the AC2 and as a top of the range set with the MC9.
The specific calibration of the inhalation mechanism slightly changes the personality of the air delivery compared to the Ellipse series, to reward, over and above the exquisite feel and sensitivity of these models, an abundant flow without the need to exploit the Venturi effect. This characteristic gives it a low tendency to continuous flow on the surface or when the equipment is in the water, ideal for schools and rental, octopus and double regulator. The performance results nevertheless place it above regulators considered to be of a higher range.
• Asymmetrical front cover perforation. The water flow starts to push the membrane in a counter-clockwise direction so that its retraction is perfectly flat and the cam descends progressively and in perfect perpendicularity, whatever the conditions (current, sudden movements, any position of the face, etc.).
• Particularly low exhalation effort without the need to reduce the thickness of the membrane. The design of the membrane retention system directs the flow 100% channelled towards the nozzles of the moustache, benefiting from a powerful Venturi effect which also helps to direct the bubbles away from the diver's field of vision. Embedded diaphragm to avoid water leaks in case of sharp turns or when jumping from the boat into the water.
• Virtually integral purge button, 80 to 400% larger than any other regulator on the market to facilitate the purge manoeuvre, especially for inexperienced divers.
• 30º bayonet twist lid assembly system, ensuring simple and safe assembly and disassembly, even for sand cleaning on the beach without the need for tools.
• Large cover locking device, removable without the need for tools. Differentiated two-stage insertion-extraction movement to prevent accidental release in the event of knocks.
• New ultra-flexible 100 cm yellow hose.
