MC11 1St Stage Only

The MC11 first stage is a hyperbalanced diaphragm system, power-packed into an ultra-compact size, ready for your global underwater explorations. The MC11 stands out in the global regulator market by using our proprietary Cressi PressureSync System, a Cressi innovation that drastically reduces the typical drop in working pressure at the beginning of the inhaling phase. Due to the Cressi PressureSync System, your entire inhalation phase will be even and fully supported by 100% of the working pressure – during every breath you take. With a total weight of only 422 g (DIN) and 569 g (INT), the MC11 is the ideal travel companion for any warm water diver. With two high-pressure ports, it also offers extra safety by allowing a redundant pressure gauge.
