first stagenitroxDIN

Overview
The redesigned C370 features optional diver-changeable color frames in six colors for quick personalization. Combined with the MK17 EVO 2, this compact and lightweight regulator system is built for global diving: a sealed-diaphragm first stage with a dry chamber on a twin-spring layout and two HP ports set at a 15° angle for easier hose routing. The compact C370 second stage provides diver-adjustable inhalation effort, a coaxial dive/pre-dive lever and a large, easy-to-activate purge button.
