2nd stage Ellipse Balanced Many of the exculsive technical characteristics of the Ellipse, covered by 4 international patents have been transferred to this new second stage. Ellipse Balanced has a slightly larger casing which is made from a sound absorbing material, and a new diaphragm that further improves the already very low inhalation effort of Ellipse. The weight is very low, only 170g (the lightest in the category). The pneumatic balancing system of this piston allows for constant performance at any depth and with any air pressure in the tanks. An easy grip know allows for the instant adjustment of the inhalation effort, even when wearing gloves. The regulation system is protected by a double seal and is fully protected from contact with water, thus maintaining smooth rotation even over time. A small leve, located in the upper part of the casing, acts as a flow deviator and allows the Venturi effect to be adjusted. When placed in position (-) it functions as pre-dive, for getting into the water and the first stages of the dive,whilst when moved to (+) it allows the regulator to develop its maximum performance. An internal heat exchanger optimises the performace of the regulator even in cold waters. The special study of air flows inside the casing has meant that absolutely natural, smooth and ery silent breathing has been obtained. The standard exhaust tee can be directly replaced by the user for the larger model, supplied as standard, which pushes the bubbles further way from the diver's face.
