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.
This is very important in Octopus regulators, since the Pre-Dive position is
much more resistant to Venturi-Free-flows that can sometimes result in
significant air-loss during a dive. The Envoy II Octopus comes with a Yellow
cover and 36" hose.
