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. 

Hard-to-miss, the Envoy II Octopus comes with a bright yellow facing that’s easily spotted in low-light conditions and a 36″ hose that yields plenty of clearance for rigging and other gear.
