A > V200 First stage
The balanced diaphragm V200 first stage reduces the
high pressure air in the cylinder to an adjustable interme-

position.
C > Venturi lever
This lever, located on the side of the second stage
Housing, enables the diver to control the inhalation
Venturi effect. When on the + position, the diver get
maximum Venturi assistance upon initial inhalation, the
air flow is maintained without additional effort.
Important : On the surface to avoid any free flow resul-
ting from surface waves and / or sudden entry in the
water , the diver should keep the lever pushed towards
the front in the - minus position. This position should be
