Envoy II Octopus
High performance with free-flow control
The economical Envoy II octopus is the same internally as the ZX 2nd stage, but does not have the adjustment knob or the heat exchanger. The Envoy II Octopus has a Venturi Control Lever that allows the diver to set the octopus 2nd stage in the Pre-Dive position until needed.
