MK11 / C300 System
The new C300 regulator with adjustable inhalation resistance and anti-scratch cover, combined with the new MK11 re-designed lightweight first stage, makes this system to the ideal regulators for travel enthusiasts and scuba divers.
 
MK11 T.I.S. first stage:
With the MK11 Scubapro engineers have devoloped a diaphragm first stage similar to the MK17 AF, except for the dry ambient champer. It is recommended for sports divers looking for the advantages of a diaphragm first stage in recreational temperatur ranges. The new MK11 (New 2011) is more compact and lightweight without affecting reliability or performance.

• Machined marine grade chrome plated brass body
• Overbalanced diaphragm design
• Safety seat guide and low profile HP orifice 
• Two High Flow Ports (HFP)
  Four stationary low pressure ports, two of them HFP. High Flow Ports deliver about 15% more air than conventional ports.
• Thermal Insulating System (TIS)
• Externally adjustable intermediate pressure
• Two high pressure ports
  Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck
• YOKE or DIN
  Available in 232 bar yoke or DIN system
• CE-Approved

C300 Second Stage:
Scubapro's compact C300 Systems offer uncompromising breathing performance for avid recreational divers. The C300 second stage is lightweight with anti-scratch cover. It allows all the adjustment options of a high-end regulator while remaining a midrange system.

• Anti scratch cover
• The Optimal Flow Design valve (OFD)
  For reliable and high air flow, improving work of breathing compared to a downstream valve.
• Diver-adjustable coaxial VIVA
  For powerful inhalation assistance and prevention of free-flow.
• Diver adjustable inhalation control
  For personalized breathing effort.
• Redesigned mouthpiece tube
  Allows better exhaust airflow. 
• Precision molded carbon fibre and technopolymer valve housing and components
  Low friction, light weight, corrosion and cold water resistant.
• Light weight orthodontically designed mouthpiece
  Comfortable and reduces jaw fatigue and gum irritation.
• Compact design
  Light weight for comfort and travel.
• CE-Approved

Scubapro introduces 2 new second stage regulators. C300 and C200 feature the new Optimized Flow Design valve for outstanding performances in a compact housing. This 3D movie shows the technical details of the valve.
