    You may be onto something there. I think some are actually labeled "Dive" and "Pre Dive." But the vane does act to direct the airflow. Making it adjustable allows it to disrupt airflow when positioned to do so.

    Last year I experimented and made a makeshift vane installed in the shank of my BA, what I found was an increased in Venturi effect while flow testing.

    It may just act as a deflector or air straightener in the BA, the old HOG classic had one that acted more like a ram air scoop, they have since quit adding these yet the boss for attachment are still there.

    I was trying to duplicate this... and it seem to work based on reduced effort at the same SCFM.

    That, by the way, is marketing at its finest.

    Do you guys actually dive these regs? This discussion is reminiscent of some of the early theoretical math work I did. I assume there is a practical component somewhere? :p

    @buddhasummer Perhaps getting them wet may be revealing?

    Writer by Pete Wolfinger, don’t we respect his knowledge and understanding of regulators?

    Marketing in a technical service manual? Hmmm

    It’s purpose was to help control free flow.
