New design of pneumatically balanced second stage. With Venus we have designed a regulator combining small size, light weight generous air – flow, reduced breathing resistance and reliable performance at low water temperatures. New controlled Venturi air flow system and sensibility control knob enhance the ease of breathing and regulator performance. It’s body is made of special technopolymer with water holes designed to limit the risk of free flow even in the strongest currents. This model is CE certfied.
