Pairing of balanced and adjustable 2nd stage Ellipse Balanced with the hyper-balanced 1st stage MC9- SC.

Thanks to the performance and the highly technological content of both stages this regulator is placed at the very top of the Cressi range.

The user can adjust both the inhalation effort and the Venturi effect (dive / pre-dive) at any time during the dive.

The 1st stage MC9 – SC is identical to model MC9, but with a special Seal Chamber which completely isolates the diaphragm and spring from contact with water.
Ideal for diving in waters that are rich in suspension and mineral salts, for archaeological work, for potholing and diving in cold waters.
