Cressi MC9 Compact Regulator and Compact Octopus Package offers a lightweight, compact, and high-performing air delivery system perfect for recreational divers and travellers. This complete set includes the advanced MC9 diaphragm first stage, the ultra-compact XS Compact second stage, and a matching Compact Octopus, providing reliable performance at an outstanding value.

Cressi XS Compact Regulator: The second stage of this regulator is the XS Compact, engineered to provide smooth, reliable air delivery even in demanding conditions. It’s paired with the MC9 first stage, known for its high performance, consistent intermediate pressure, and low weight—ideal for divers who travel frequently or dive in temperate waters.

The design focus of the Cressi XS Compact / MC9 system lies in its ultra-lightweight construction, ease of breathing, and resistance to freezing. Maintenance is straightforward, making it a great choice for divers of all experience levels.

Cressi MC9 First Stage Features:

• Self-Lubricating Jacketed Cylinder: Improves long-term performance and reliability by reducing friction and wear inside the first stage piston.
• Removable Stainless Steel Nozzle: Increases durability and simplifies servicing—ideal for divers who log frequent hours underwater.
• Anti-Pressure Drop Pneumatic Spring: Ensures stable intermediate pressure, delivering consistent airflow to the second stage even as tank pressure drops.
• Sintered Filter Cup: Captures fine particles and impurities before they enter the regulator, providing cleaner air and protecting internal components.
• 4 Low-Pressure Ports & 2 High-Pressure Ports: Offers flexible hose routing for your BCD, alternate air source, pressure gauge, or dive computer.
• Techno-Polymer Body: Strong, lightweight, and corrosion-resistant construction for durability and travel-friendly performance.
• Dive/Pre-Dive Adjustment Lever: Allows divers to control venturi effect to prevent free-flow when not in use, and boost airflow during active breathing.

Cressi XS Compact Octopus: Sharing the same advanced design and casing as the XS Compact second stage, the Compact Octopus is distinguished by its bright yellow faceplate and hose for high visibility in emergency situations. Made from ultra-lightweight materials, it offers excellent comfort and reduced jaw fatigue—especially important when used as a backup air source.

To reduce the likelihood of free-flow in storage or in transit, the Compact Octopus is calibrated to require slightly more inhalation effort than the primary second stage. This thoughtful design ensures that it performs reliably when needed while remaining secure and dormant when not in use.

Cressi XS Compact Octopus Features:

• Streamlined, Low-Profile Shape: Minimises drag in the water, making it easier to handle and more streamlined when clipped to your gear.
• Oversized Purge Button: Nearly covers the entire face, making it quick and easy to locate and use—even with gloves.
• Lightweight Build: Reduces jaw fatigue and adds comfort during long dives; ideal as a travel octopus.
