The new 500SE utilizes a servo controlled valve to provide precision airflow and unparalleled performance for both air and trimix divers in a side exhaust configuration.

The regulator is designed to meet the strict CE standard for cold-water performance, and its environmentally sealed first stage ensures the delicate internal parts remain protected from contaminants like salt, sand, and chlorine.

The DC7 First Stage Regulator features a secondary diaphragm that completely seals the main spring cavity, providing excellent resistance to freezing or corrosion in icy or contaminated waters. Crafted from marine-grade brass with a black anodized finish, the first stage offers four low-pressure (LP) and two high-pressure (HP) ports for optimal hose routing in both back-mount and side-mount configurations. Nitrox compatible up to 40%, this regulator requires less maintenance than models that expose internal mechanisms to contaminants.

The 500SE Second Stage utilizes a servo-controlled valve in a side exhaust configuration to deliver unparalleled performance for both air and tri-mix divers. Its innovative design ensures a gentle inhale activates the valve, providing increased airflow through multiple ports. This pneumatically balanced regulator features a large soft purge cover for easy clearing, a patented orthodontic mouthpiece for comfort, and can be configured for left or right positioning without any upside-down issues.
