Description

Simple and reliable, the MK2 EVO/R105 is the regulator system of choice for diving
schools, rental centres and new divers, as well as avid recreational divers looking for
a basic backup breathing system. It offers smooth dependable air delivery and is built
to last. The compact casing is based on the S620 Ti with an anti-scratch front cover
and a metal classic downstream valve design. Included is a dive/pre-dive VIVA switch
plus a soft, co-molded purge button for easy purging, and left or right hose routing
for use on stage or pony bottles. Teamed with SCUBAPRO’s classic MK2 EVO, the only
downstream piston-style first stage with internal components specifically designed
to resist freezing in extreme cold-water conditions, this regulator combo is durable,
reliable and affordable.

MK2 EVO FIRST STAGE
◊ Classic downstream piston design features a chrome-plated marine-grade brass
body with one high pressure and four low pressure ports.
◊ Patented XTIS (Extended Thermal Insulating System) fully isolates the mechanical
elements from the cold, increasing freezing resistance by an average of 50% over
its predecessor without compromising breathing performance.
◊ Additional internal technical improvements include a spring insulating bushing and
coating, an insulating piston bushing, an insulating sleeve and an antifreeze cap,
all of which contribute to freezing resistance.
◊ Chrome-plated marine-grade brass body is smaller than its predecessor but
houses an oversized piston that provides better breathing performance by
increasing airflow.
◊ Stainless steel removable orifice allows for easier maintenance while extending
regulator life.
◊ Meets EN250-2014 standards for cold-water breathing performance.
◊ Weight: INT 232, 670 g / DIN 300, 450 g.
◊ Intermediate pressure (bar): 9.5-10.

R105 SECOND STAGE
◊ Classic downstream valve comes with a dive/pre-dive VIVA switch to control free
flows.
◊ Metal valve housing is built rugged and increases overall reliability.
◊ Reversible hose attachment makes it easy to use for side mount, pony or deco
tanks.
◊ Super-flow hose features an oversized bore that allows more air to flow on each
inhalation.
◊ Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all
mouth sizes, from largest to smallest.
◊ CE certified according the latest EN250A European Standards for all diving
conditions, including extreme cold water.
◊ Weight (without mouthpiece): 156 g.
