Cressi MC9-SC/Compact Pro Dive Regulator - INT

Performance and reliability for true diving professionals

The Cressi MC9-SC/Compact Pro Dive Regulator is truly a product for true diving professionals, as it is known for its performance, ergonomic reliability, and ease of maintenance.

In order to achieve extremely high performance in low temperature environments, the second stage in particular was designed with the special Thermoconductive Thermoplastic Neopolymer that has the capacity to transfer heat like a metal while preserving the design flexibility, chemical resistance, and physical and mechanical properties of a conventional thermoplastic. That is, it makes it possible to drastically reduce the weight while delivering heat conductivity on a par with metal cases. Thanks to this material and a specially conceived purge valve, it can pass all the tests for use in cold water with flying colors.

The MC9-Sealed Chamber
1^st stage
Environmentally-sealed, protecting it against icing in cold water and against contamination from particulate matter in silty conditions. When paired with the Ellipse Balanced second stage, which includes an internal heat exchanger, this regulator is an excellent choice for divers exploring the most extreme cold water
environments.
