The new, larger injector in high-tech polymers delivers the air directly to the mouthpiece, making the renewed Cressi-sub I.B.I. (Internal Balance Injection) system even more efficient.

This model also has a practical, easy to use flow control valve which exploits the Venturi effect created by theI.B.I. system to the full.
The new profile of the on lever for the nozzle creates a perfect seal with the membrane disk.
The significant fulcrum and the almost total absence of friction enable the air to flow freely. The resulting Venturi effect reduces inhalation effort to a minimum even in the most challenging conditions.
First Stage
The unbalanced 1st stage is more compact and lighter, producing outstanding performance which matches that of a balanced piston model.
The dynamic, cutting-edge design includes two pairs of low pressure ports which come ready-angled to ensure perfect connection with the 2nd stage connectors and instruments, making diving more comfortable.
Calibration is quick and easy thanks to Cressi's exclusive rotating ring nut system- the only one of its kind. As a result the device can be adjusted quickly and accurately using a caliper-type key without dismantling the regulator.

Inside the regulator there is a powerful conical filter which has a 200% greater filtering capacity than standard flat filters.
The device has a significant air capacity (maximum 2.100 liters/minute ) thanks to wider hoses which guarantee both comfort and safety.
The rod and DIN type connector (300 bar) are fully interchangeable and easy to replace.
The robust, completely reliable, easy to use 1st stage has an attractive satin finish and is built with outstanding materials and all of Cressi-sub's years of know-how.
