The Cressi MG Octopus regulator specially designed for the most demanding divers. Perfect for a Hookah Diving Regulator / Compressor Diving Regulator as it is pneumatically balanced. Its main feature is a pneumatically balanced valve that minimises the breathing effort. The Venturi effect adjuster on the mouthpiece tube increases and decreases the air flow, doing away with the risks associated with free-flow. When scuba diving, breathing is natural and effortless. Thanks to its light weight and ergonomic design, this regulator is very handy and easy to use.
