Περιγραφή
SCUBAPRO’s flagship regulator system is designed for divers who want the best.
The MK25 EVO offers excellent resistance to freezing, superb inhalation sensitivity
and instant delivery of air on demand. The A700 offers effortless inhalation and an
ease of exhalation that is unmatched in a precision-handcrafted, full-metal package.
Together they provide unparalleled breathing performance in all water temperatures.
MK25 EVO FIRST STAGE
◊ 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
◊ Patented XTIS (Extended Thermal Insulating System) fully insulates the inner
mechanism from the environment, improving cold-water resistance by 30% and
delaying ice formation in extreme cold-water conditions without compromising
breathing performance. Key insulation system components are visible in blue.
◊ 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.
◊ Four high-flow and one axial super 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.
◊ Weight: INT 232, 790g; DIN 300, 572g.
◊ Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
◊ Intermediate pressure (psi/bar): 133-142/9.2-9.8.
A700 SECOND STAGE
◊ Air-balanced valve smoothes out the inhalation effort at varying depths and supply
pressures
◊ Rugged full-metal case, front cover and valve housing (barrel) are able to
withstand years of aggressive diving
◊ Metal construction enables the use of a larger diaphragm inside a compact casing,
increasing breathing sensitivity
◊ User controls include a diver-adjustable inhalation effort knob and coaxial-flow
Venturi-Initiated Vacuum Assist (VIVA) lever
◊ Super-flow hose features an oversized bore that allows more air to flow on each
inhalation
◊ Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit
airflow
◊ CE certified according the latest EN250A European Standards for all diving
conditions, including extreme cold water.
◊ Airflow at 200bar: 2000 l/min
◊ Weight (without mouthpiece) 9.2oz/261g.
S270 OCTOPUS
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
