CMC Podcast 10 - AZ Vortex (Part I of II) Belay High, Low or Through an AZTEK?


 Contributors in this Episode


This episode discusses what we do with our belay line when using an artificial high directional like an Arizona Vortex. Do we put it high through the Vortex along with our main or second line, do we run it low along the ground or do we do something in between like suspending it temporarily from an AZTEK kit? Tune in to this round table discussion with CMC School instructors.
