Simple and reliable, the MK2 EVO/R105 is an ideal regulator system for dive schools, rental centers and new divers, as well as those seeking an affordable backup system. It delivers smooth, dependable airflow in a compact design with a scratch-resistant front cover and classic metal downstream valve. Features include a dive/pre-dive VIVA switch, soft purge button and reversible hose routing for stage or pony bottles. Paired with the MK2 EVO, designed to resist freezing in extreme cold water, this regulator system is durable, reliable and cost-effective.
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 anti-freeze cap, all contributing to enhanced freezing resistance.
• The chrome-plated marine-grade brass body is smaller than its predecessor but houses an oversized piston that improves breathing performance by increasing airflow.
• Stainless steel removable orifice allows 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: 9.5–10 bar
Second Stage
• Classic downstream valve includes a dive/pre-dive VIVA switch to control free flows.
• Rugged metal valve housing increases overall reliability.
• Reversible hose attachment makes it easy to use for sidemount, pony or deco tanks.
• Super-flow hose features an oversized bore that allows more air to flow with each inhalation.
• Compact Hi-Flow mouthpiece improves airflow and comfort, fitting all mouth sizes from largest to smallest.
• CE certified according to the latest EN250A European Standards for all diving conditions, including extreme cold water.
• Weight (without mouthpiece): 156 g
Octopus
• Classic downstream valve design for optimal breathing performance.
• Rugged metal valve housing increases overall reliability.
• Preset inhalation and Venturi Initiated Vacuum Assist (VIVA) provide hassle-free air delivery.
• Reversible hose attachment makes it easy to use for sidemount, pony or deco tanks.
• Ultra-comfortable orthodontic mouthpiece is easy to grip without restricting airflow.
• Includes yellow purge cover and a 39 in / 1 m high-visibility yellow hose.
