The MK2 Evo first stage combined with the R105 second stage is a simple but reliable unbalanced regulator system, very popular among diving schools for rental, beginners as well as experienced recreational divers as backup regulator. Durable, built to last and delivering smooth, dependable air.
The R105 features a compact casing based on the S620 Ti, including anti-scratch front cover and metal classic downstream valve design, a dive/pre-dive VIVA switch, co-moulded soft purge button and reversible hose routing for use on stage cylinders.
The MK2 Evo is the only downstream piston-style first stage designed to resist freezing in cold waters.
Finally, this Scubapro regulator combo is durable but 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 Yoke Version 670gr / Weight DIN 300 Version: 450gr.
Second Stage Features:
- The classic downstream valve comes with a dive/pre-dive VIVA switch to control flow.
- 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.
- CE certified according the latest EN250A Standards for all diving conditions, including cold water.
- Weight (without mouthpiece): 156gr.
