Is there a dive/predive switch or de-tune lever on the Envoy Octo.
If there is, do you open it when you dive or what ? easy to forget maybe ?

Nope. At least mine doesn't.

It's my understanding that the dive/predive lever is to prevent free-flow (when on "predive") and to allow easy breathing (when on "dive.")

That works very well on your primary second stage.

But on an octo, you don't want to have any free-flow, so it's a bit "detuned." It'll be a bit harder to breath, but when needed no one is going to mind.
