Regulator Cressi MC9 XS Compact Pro

Regulator is the master of cold water and for travel junkies.

Combines a balanced diaphragm first stage with an SC cold water system with a sealed chamber and a light and compact second stage, that is a high performer in waters colder than 10°C.

This premiere travel regulator packs maximum performance into minimum space. A true featherweight second stage, the XS Compact Pro is built from lightweight techno-polymers to eliminate jaw fatigue. Easy to pack and easy to dive, the XS Compact Pro s dive/pre-dive Venturi switch for managing freeflow and maximising performance at depth. It's perfect if you're looking for a combination of performance, reliability and low maintenance costs.

MC9-SEAL CHAMBER 1ST stage
The MC9-SEAL CHAMBER 1ST stage is environmentally sealed, protecting it against icing in cold water and against contamination from particulate matter in silty conditions.
The 1st stage MC9-SC is identical to model MC9, but with a special Seal Chamber which completely isolates the diaphragm and spring from contact with water. This makes it ideal for diving in waters that are rich in suspension and mineral salts, e.g. for archaeological work, cavern, scallop/cray, and diving in cold waters.
Hyper-balanced Diaphragm 1st stage with highly technological content that places it at the top of the Cressi range.
Very light body covered by a protective elastomer shell.
Cylinder sheathed in an anti-friction and anti-corrosion material that guarantees perfect sliding of the piston and long maintenance intervals.
The nozzle, made from 316 stainless steel, can be easily d, thus ensuring perfect air-tightness, even after many years of use.
Advanced research on the passage of internal air and a special assistance chamber have enabled the drop of pressure upon inhalation to be kept to a minimum, thus guaranteeing high performance in any situation.
Hyper-balancing allows for an increase of the intermediate pressure at maximum depths and lowering of the pressure in the tank, offering higher performance during the delicate ascent phase and at maximum depths.
DIN 200/300 bar fitting in stainless steel which prevents deformation of the thread in the event that the regulator suffers any falls.
