With the 2nd stage Ellipse Balanced Cressi Sub , you'll have a product of excellent quality, from very low weight, with a chest size slightly increased, and a new diaphragm that further improves the amount of inhalation effort of Ellipse.

Really useful in the system of pneumatic balancing piston, which allows you to have consistent performance at any depth and with any air pressure in the cylinders.

A knob allows you to instantly adjust the breathing effort, while a lever which acts as a flow diverter, which is placed in the upper part of the case that allows you to adjust the Venturi effect: moved to position (-) works by pre-dive, for entering the water for the initial stages of the dive, while pushing on the (+) allows the regulator to develop its maximum performance.

An internal heat exchanger optimizes the performance of the regulator even in cold waters.

With regard to the 1st stage MC9 SC - 300din of Cressi Sub has been designed with a body very light, covered by a protective shell elastomers, while a special Seal Chamber island totally diaphragm and spring from contact with water.

On the 1st stage MC9 SC - 300din a study was undertaken of the steps in the internal air and a special room service that have allowed us to reduce to a minimum the pressure drop at the moment of inspiration, thus guaranteeing high performance in any situation of use.

The nozzle is made of stainless steel 316, is replaceable, so as to always have a perfect air-tightness, even after many years of use.

The iperbilanciamento allows to obtain an increase of the intermediate pressure at maximum depths and lowering of the pressure in the tank, offering higher performance during the delicate phase of the ascent and to the maximum depth.
