Premium breathing performance in all conditions. Scubapro's ultimate S600 second stage regulator paired with an all-rounder balanced diaphragm MK17 for best breathing, even in harsh environments.
A high performance balanced diaphragm first stage regulator, the MK17 has been engineered for harsh environments and for use in ice cold water or polluted environments. Resistance to cold has indeed been a key element in the engineering of the MK17.
A second stage regulator must translate natural breathing behaviour into mechanical reality. A high quality second stage can significantly reduce stress and enhance diver safety by providing smooth, low-effort breathing response, resulting in ample yet controllable quantities of air.
