MK17 Evo/R195 Regulator

MK17 Evo/R195 Regulator with a first stage that's environmentally sealed and a smooth-breathing second stage that's easy-to-use, this is a versatile  and  reliable  breather  for  recreational  divers. The new MK17 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. It is more compact yet delivers better breathing performance than its predecessor. Its improved internal design allows more airflow from the LP ports which have been reconfigured for better hose routing.

The R195 is a new design based on the heritage of the classic R190 second stage, re-engineered with modern features and materials. The R195 combines a classic downstream valve with a large diaphragm and classic purge button. Its simple and robust construction offers the utmost in reliability and makes the R195 the ideal second stage for new divers and a perfect choice for deco tanks thanks to its reversible hose attachment.

MK17 EVO First Stage:

• Air balanced diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
• More compact design features a smaller dry ambient pressure chamber and spring, although the bulletproof inner parts remain the same.
• Dry ambient pressure chamber increases freezing resistance, ensuring consistent airflow in the coldest conditions.
• Substantial increase in airflow -- 6900 l/min versus 6500 l/min -- includes improved balance of air supply pressure.
• Two high pressure and four high-flow ports maximize air delivery and hose routing options.
• High-flow performance is available from all four LP ports which are configured for optimum hose routing.
• Available in a 3364psi/232bar INT configuration.
• Weight: INT 232 - 30oz/850g.
