Cressi Ellipse Black Balanced MC9 Scuba Diving Regulator

Pairing the balanced adjustable Ellipse 2nd stage regulator, with the hyper-balanced diaphragm 1st stage MC9 regulator, place this regulator at the very top of the Cressi range. The engineering and performance of this combination creates a high performance regulator that will compete with the best of them.
The Ellipse Balanced 2nd stage has incorporated many of the characteristics of Ellipse. The Ellipse Balanced has a slightly larger housing which is made from a sound-absorbing material, and a new diaphragm that further improves the already very low inhalation effort of Ellipse. The pneumatic balanced piston allows for constant performance at any depth and with any cylinder pressure in the Scuba tank. The design of the 2nd stage is environmentally sealed allowing the regulator to function properly between annual services at a constant high performance. An internal heat exchanger optimizes the performance of the regulator even in cold waters. Through an engineering study of the internal air flows of the housing Cressi engineers have created an absolute natural, smooth and very silent breathing capability. 

The Balanced 1st stage MC9 Hyper-balanced Diaphragm Actuated 1st stage has a lightweight body covered by a protective techno-polymer elastomer shell.
