Scubapro MK25 EVO/S620 Ti Regulator Stage 3 Set

*Stage 3 sets come with 1st stage, 2nd stage and octo*

This regulator system combines Scubapro's premium high-performance MK25 EVO first stage with its latest high-performance S620 Ti second stage to create a winning all-purpose, all weather regulator system. The MK25 EVO offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand.

The new S620 Ti boasts a long list of design features guaranteed to enhance a diver’s underwater experience. Offering improved work of breathing in a smaller and lighter package, the S620 Ti is built tough: you’ll find a corrosion-free titanium barrel inside a rugged reinforced technopolymer case and front cover with a new, larger stainless steel frame reinforcement.

The set includes a highly reliable R195 octopus with an extra-long visibility hose and reversible hose attachment.

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) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing 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 maximise hose routing options.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.

SECOND STAGE:

• Rugged reinforced technopolymer case and front cover with stainless steel frame is able to withstand years of aggressive diving.
• Lightweight titanium barrel is rugged and corrosion resistant, and will last virtually forever no matter what environment it faces.
• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• Large diaphragm fits inside a compact casing for maximum breathing sensitivity.
• User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
• Large purge button is designed with holes to improve water circulation.
• Flow-engineered high performance exhaust tee improves ease of exhalation.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Newly designed Compact Hi-Flow mouthpiece, exclusive to the S620 Ti, is mounted on an enlarged mouthpiece pipe to improve airflow as well as mouth comfort.

OCTO:

• 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 freeflows when not being used

• Compact and efficient exhaust tee minimises exhalation effort

• 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

• 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.
