Simple and reliable, the Scubapro Mk2 EVO/R105 Regulator 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 new regulator combo is durable, reliable and affordable. 

FIRST STAGE Features:

• 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 new EN250-2014 standards for cold-water breathing performance.
• Weight (oz/g): INT 232, 23.6/670; DIN 300, 15.9/450.
• Airflow at 2900psi/200bar: (l/min/SCFM): >3000/106.
• Intermediate pressure (psi/bar): 138-145/9.5-10.

SECOND STAGE Features:

• The classic downstream valve comes with a dive/pre-dive VIVA switch to control free flows.
• The metal valve housing is built rugged and increases overall reliability.
• The 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): 5.5oz/156 g.
• Airflow at 2900psi/200bar: 1200 l/min - 42 SCFM.
