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.
