Scubapro MK19 EVO/D420 Dive Regulator System

Designed for avid divers everywhere, the K19 EVO first stage with balanced diaphragm is paired with the next-generation D420 balanced second stage for easy breathing and diving comfort in all dive scenarios. The D420's uniquely shaped, ultra-durable fiberglass-reinforced nylon casing allows the LP hose to be connected on either the right or left side for maximum rigging flexibility. IInner 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. Other features include a large purge button that's easily operated with or without gloves, a compact Hi-Flow mouthpiece for improved airflow and comfort, and four high-flow and one axial super high-flow low pressure ports on a swivel turret. 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. An air-balanced diaphragm first stage has more moving parts than a piston first stage, but its body is environmentally sealed . Driven to constantly innovate and improve the diving experience, SCUBAPRO builds flawless equipment for the work, sport, and lifestyle of people whose passion is found below the surface.
