AMGA Single Pitch Instructor Anchor Demo: V-Rig/ Joshua Tree Anchor System with Instructor Tether

Jeffrey Mascaro, AMGA SPI Provider, Certified Alpine, and Rock Guide, demonstrates one way of building an institutional anchor in single-pitch terrain using a static rope while also incorporating an instructor tether.

This system excels when building top roping anchors with natural features while keeping the anchor builder secure/ attached to the mountain during the process.

Great video! Thanks for taking the time to show a nice thorough example of the v-rig.

This is an outstanding video, thank you for sharing! The little bowline overhand tip is top notch too.

Question from an aspiring SPI. Before you clipped the static rope to the gear leg of the anchor, my inclination was to remove the carabiner from one of the cam slings, basket that cam sling with a shoulder length sling and clip the ends to the other cam with both carabiners, opposite and opposed. Configure the shoulder length sling in a sliding X then connect the static rope to it with a locking carabiner and an overhand. I know it’s less efficient on your materials, but I thought that the slabby rock might cause an issue with the carabiner’s gates and cause them to open. What do you think?
