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.
