Which technique is recommended when using carabiner-axe belays?

When utilizing carabiner-axe belays, attaching the carabiner to the top of the axe with a short runner is the recommended technique because it ensures that the belay system maintains optimal strength and efficiency. This method allows the carabiner to pivot around the axe, which aids in reducing the likelihood of cross-loading and increases the overall stability of the system. The use of a short runner minimizes the distance between the carabiner and the axe, enhancing control and response during a rescue operation.

The engagement of the belay device through the carabiner connected to the axe is critical since it allows for effective load management, providing better security for both the rescuer and the person being belayed. This technique also aligns with best practices in safety and efficiency when navigating challenging terrain or during recovery scenarios where stability is paramount.

Other options would not provide the same level of safety and effectiveness. For example, using only one carabiner may reduce redundancy and could lead to a failure in the belay system. Not attaching the rope to the belay device compromises the entire belay function, making it unsafe for both the rescuer and the subject. A long rope with no knots could create excessive slack and prevent the proper management of dynamics in
