Mk19 Evo/ D420

Was $899.00     Now $749.00

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. 
 

MK19 EVO / D420 Dive Regulator System

Dive confidently with the SCUBAPRO MK19 EVO/D420 regulator set, which combines the high-performance MK19 EVO first stage with the D420 second stage to create a premium regulator system.

Combining the iconic design of the original D-Series regulators with the latest advances in breathing performance technology, the D420's new air-balanced Progressive Flow Control Valve delivers abundant airflow with a natural smoothness comparable to breathing on the surface.

The D420 also features a uniquely shaped, fiberglass-reinforced nylon casing that allows the LP hose to be connected on either the right or left side for maximum rigging flexibility.

Smooth Operation
The perfect blend of rich diving history and cutting-edge regulator technology, the D420 features inner winglets that direct airflow towards the exhaust valve for optimal exhalation and a switch-operated dive/pre-dive system on the top of the casing for adjusting the direction of airflow right out of the valve.

A large purge button is easy to reach and depress with or without gloves, and the compact exhaust tee deflects bubbles from your view.

Effortless Air Delivery
The MK19 EVO air-balanced diaphragm first stage delivers effortless airflow that's unaffected by depth, tank pressure, or breathing rate. It features a new dry chamber that's equipped with a double spring to make it more compact and reliable.

Four high-flow LP ports plus one axial super high-flow LP port maximize hose routing options.

Benefits of Diaphragm Technology
An air-balanced diaphragm first stage like the MK19 has more moving parts than a piston first stage. However, its body is environmentally sealed to prevent water and pollutants from fouling the inner mechanism.

Because of this, it's a great choice for divers who find themselves in waters containing lots of suspended particles, silt, or contaminating materials.
