Description:
The Delta 4 uses our pneumatically balanced valve with dynamic inhalation
adjustment for hassle free control over the performance level of the second
stage. The inhalation control on the side of the Delta 4 allows a performance
level to be set by the diver which will be automatically maintained by the
second stage itself. There is no need to manually adjust the controls as depth
increases or decreases as this is adjusted by our Dynamic Adjustment assembly.
The Delta 4 also features a venturi switch on the top of the body to allow the
diver to control the air flow and venturi effect within the housing, switching
between Pre-Dive and Dive modes as needed. In Pre-Dive mode air is directed back
into the housing to help prevent free flows and the Dive mode directs air
towards to the mouthpiece for maximum performance.
