Dismantling: second belay point and evacuation system on the ZIGZAG in single mode with CHICANE

Note: in this document the name ZIGZAG means either the ZIGZAG or ZIGZAG PLUS models.
During cutting operations, the arborist must use two belay systems.
The positioning lanyard is the first system.
The ZIGZAG, installed on a choked anchor, serves as the belay system as well as the evacuation system.
The ZIGZAG is not designed for working in single mode without an auxiliary brake.
To recover your equipment, connect the other end of the rope to the "choke" carabiner.
