The Scubapro Mk19 EVO S620Ti/S270 Regulator Set smooth-breathing S620 Ti, embracing the best features of SCUBAPRO’s renowned S600 in an upgraded design that delivers 37% lower work of breathing, is a proven performer when it comes to providing effortless airflow. Put them together, and you have a versatile regulator system that can be counted on to deliver top-line performance in all dive conditions.

FEATURES:

FIRST STAGE 

• Designed to be the ultimate first stage for cold water or contaminated diving conditions.
• Its design makes it substantially smaller and lighter than the original MK19.
• Air-balanced flow-through piston in a chrome-plated marine-grade brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate
• An environmentally sealed system prevents water and pollutants from fouling the inner mechanism. ◊ Its dry chamber is equipped with a double spring, making it more compact and reliable.
• Two opposing high-pressure ports allow the first stage to be positioned either up or down, plus provide for an optimum hose/transmitter layout.
• The swivel turret comes with four High-Flow LP ports plus one axial Super High-Flow LP port to maximise hose routing options.
• Compact size, lightweight and superb breathing performance continue in the best SCUBAPRO regulator tradition.
• The ideal first stage for recreational, technical, professional and military divers.
• Weight: INT 232, 885g; DIN 300, 665g
• Airflow at 2900psi/200bar: (l/min/SCFM): >6,900/244
• Intermediate pressure (psi/bar): 133-142/9.2-9.8

SECOND STAGE

• 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.
• The 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.
• The 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.
• Airflow at 200bar: 1850 l/min ◊ Weight (without mouthpiece): 179g

OCTOPUS S270 

• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Lightweight casing, made of a fibreglass-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 extremely cold water.
• The dive/predive switch prevents free flows when not being used.
• The exhaust tee is compact and very efficient in minimising exhalation effort.
• The compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone and features a large cross-section to maximise airflow.
• High-viz yellow front cover stands out, making it easy to spot when needed.
• The 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
