The Scubapro MK17 EVO 2 / S620 Ti regulator system offers compact and comfortable breathing performance, making it an unbeatable choice for cold or silty water diving. The MK17 EVO 2 is a significant upgrade from its predecessor, the MK17 EVO, and the . It features a new forged body and a dry chamber with a twin-spring layout, enhancing reliability and reducing size and weight.

The S620 Ti second stage incorporates the best features of Scubapro’s renowned S600 into a modern, state-of-the-art design. Smaller and lighter than the S600, it retains the same-sized diaphragm, ensuring exceptional performance and effortless airflow in any dive condition. The full titanium inlet tube is ultra-light, while the large purge cover improves water circulation, and the exhaust tee enhances performance by directing bubbles out of the diver's field of view. This advanced regulator system is designed to deliver top-notch performance and comfort in challenging environments.

FEATURES:

FIRST STAGE MK17 EVO:

• NEW design allows it to be substantially smaller and lighter than the MK17 EVO and the MK19 EVO.
• Design is based on a forged brass body and a dry chamber with a twin spring layout for compactness and reliability.
• Sealed balanced diaphragm design makes for the ultimate compact first stage for cold water or contaminated diving conditions.
• Air-balanced diaphragm delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
  
• Dry chamber is completely environmentally sealed with a unique dual diaphragm system that keeps out contaminated water. The rib is designed to enhance heat exchange, making the first stage cold water-proof.
• Two opposing high-pressure ports positioned on a 15º angle allow the first stage to be positioned either up or down, plus provide an optimal hose/transmitter layout.
• Due to the high-pressure port positioning, a transmitter adapter is not needed.
• Weight: INT 232: 797g ; DIN 300: 572g
• Intermediate pressure (230 bar): 9.2-9.8

SECOND STAGE S620 TI:

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
  
• Rugged reinforced technopolymer case and front cover are able to withstand years of aggressive diving.
• Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
• Uses the S600’s large diaphragm inside a compact casing for maximum breathing sensitivity.
• Diaphragm fits inside a more compact casing for maximum breathing sensitivity.
• User controls include an easy-grip diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever.
• The exhaust tee increases performance while directing bubbles out of the field of view.
• Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water.
• Weight (without mouthpiece): 179g
  

OCTOPUS S270 BALANCED:

• The S270 Octopus is tough, reliable, and easy to use. Its air-balanced design can be counted on to deliver top-notch breathing performance when you need it most.
• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Lightweight casing, made of a fiberglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improve diving comfort.
• Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can’t grab onto when diving in extreme cold water.
• Dive/predive switch prevents free flows when not being used.
• Exhaust tee is compact and very efficient in minimising exhalation effort.
• Compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone and features a large cross-section to maximize airflow.
• High-viz yellow front cover stands out, making it easy to spot when needed.
• High-viz yellow super-flow hose is 39in/1m long with an oversized bore that allows more air to flow on each inhalation.
• CE certified to the latest EN250A European Standards for all diving conditions, including extreme cold water.
