Scubapro MK25/S600 System

Scubapro's best-selling air-balanced second stage and its top-performing air-balanced piston first stage is a match made in diver heaven.

The high performance MK25 EVO/S600 reg system is well-known for its low work of breathing and tremendous reserve capacity. Year after year it is consistently ranked as one of the top-performing regs on the market.

The MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow -- regardless of how cold the water is. This is made possible with Scubapro's exclusive patent-pending Extended Thermal Insulating System (XTIS) that fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over previous versions of the MK25 without compromising breathing performance. This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures.

The S600, with its rugged fiberglass casing and stainless steel front face and ring, delivers smooth and easy inhalation and exhalation while offering efficient user controls, including a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch. It provides a steady, effortless flow of air, regardless of depth or workload.

Synonymous with Scubapro quality and unbeatable engineering, the MK25 EVO/S600 is the preferred combo of professionals. In all water temperatures, in the most demanding dive conditions, this reg performs flawlessly.

Scubapro MK25 EVO first stage:

• Air balanced flow-through piston
  In a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patented XTIS (Extended Thermal Insulating System)
  Fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous MK25 without compromising breathing performance. Key insulation system components are visible in blue.
• New spring insulating coating
  Body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
• Anti-freeze protection
  Radically increases breathing reliability when diving in the most extreme water temperatures.
• Two opposing high pressure ports
  Allow the first stage to be positioned either up or down.
• Five high-flow low pressure ports
  On a swivel turret maximize hose routing options.
• External intermediate pressure adjustment
  Enables technicians to fine-tune performance quickly and easily.
• International or DIN Confirguration
  Available in either 232bar INT or 300bar DIN configurations.

Scubapro S600 Second Stage:

Our best selling high performance air balanced second stage incorporating numerous patented features. This second stage will optimize your diving experience by virtually eliminating any breathing effort.

• Air balanced linear flow valve
  Highest performance in any condition.
  Increases safety and relaxation on every dive, beacuse it initiates airflow effortlessly and instantly on demand, independent of the cylinder pressure in a controlled and natural manner.
• Precision molded carbon fibre and technopolymer valve housing and components
  Low friction, light weight, corrosion and cold water resistant.
  Exceeds CE cold water norm.
• Diver adjustable inhalation control
  To decrease or increase inhalation efforts for all diving conditions and diver preferences.
• Diver adjustable VIVA
  VIVA in the MAX position is a powerful breathing support. In conditions of cold water, strong current or buddy breathing,
  VIVA should be reduced to avoid free flow
• High flow exhaust valve
  Lowest exhalation effort for best breathing comfort.
• Light weight orthodontically designed mouthpiece
  Comfortable and reduces jaw fatigue and gum irritation.
• Compact design
  Light weight for comfort and travel.
• Airflow
  1.850L / Minut.
• Weight
  193g.
• Big soft purge and oversized controls.
