- 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 effortless airflow unaffected by depth, tank pressure, or breathing rate.
- Reversible hose attachment allows for either left- or right-side LP hose connections for maximum rigging flexibility
- Large purge button is easy to reach and depress, with or without gloves.
- Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing ease of exhalation
- Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
- Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
