    You are correct, we will update our information. But, with the Coaxial flow, Diver adjustable inhalation and VIVA system this regulator performs very well.

C300 Second Stage

OFD - Optimal Flow Design
This latest mechanical system provides unrivaled performance among unbalanced second stages, a worry-free intermediate solution offering high-end performance for avid recreational divers. The Optimal Flow Design (OFD) concept allows an innovative valve design where airflow is not affected by the spring responsible for the inhalation resistance. By removing the spring from the path of the air exiting the valve the flow is much smoother and the performancces are higher than a common downstream valve design.

Co-Axial VIVA Control

Allows the diver to adjust the inhalation assistance and prevents free flows when the second stage is used as an octopus.

Co-axial Inhalation Effort Control

Conveniently located, it allows the diver to adjust the inhalation effort at any time.

High-Flow Exhaust Valve

Offers an extremely low exhalation effort and contributes to lowering the overhall work of breathing.
