First And Second Stage Features - Scubapro MK25T Handbuch

Coaxial fl ow
The valve outlet is positioned coaxially in front of the mouthpiece, directing the air fl ow
straight towards the diver's mouth. The absence of curves or corners means no turbulence
or fl ow reduction and higher breathing performance.
