When raising with tandem prusiks, what should you focus on with the prusiks?

When raising with tandem prusiks, focusing on pulling slack out of the line at the same rate as the main line ensures effective and efficient movement during the raising process. This technique allows both prusik knots to engage properly and maintain their grip on the rope, facilitating a smooth and controlled ascent.

If slack is not managed correctly, it can lead to uneven tension, which might cause the prusiks to slip or the load to become unstable. By synchronizing the slack removal with the movement of the main line, you help ensure that the system operates smoothly and reduces the risk of complications during the operation.

This focus on rate of slack removal also allows for better communication and coordination among rescuers, as they will know they are all working together in a unified manner to raise the load in a consistent and supportive way.
