MK19 EVO/D420 - YOKE

• The MK19 EVO first stage with air balanced diaphragm is paired with the next-generation D420 balanced second stage for natural breathing and diving comfort in all dive scenarios.
• Air-balanced Progressive Flow Control Valve delivers abundant airflow with an natural smoothness comparable to breathing above water.
• Inner winglets within the D420's case direct airflow towards the exhaust valve dramatically improving exhalation effort, while a diaphragm lower in the casing takes advantage of the pressure gradient in the upright position for easier breathing.
• The Dive/Pre-Dive System adjusts the direction of the airflow right out of the valve by adjusting the thumb tab switch on top of the casing.
• Ideal for waters containing lots of suspended particles or silt, the compact MK19 EVO first stage's air-balanced diaphragm delivers e?ortless air?ow una?ected by depth, tank pressure, or breathing rate.
