With the MK17 EVO 2/C370 you have a compact and lightweight regulator system ready to explore dive locales the world over. The new MK17 EVO 2 is a sealed diaphragm first stage with a dry chamber based on a twin spring layout and two HP ports at 15-degree angle to make hose routing easier. The compact C370 offers convenient user controls including a diver-adjustable inhalation effort knob, a coaxial dive/pre-dive lever and a large, easy-to-activate purge button.
