The "self-tending" prusik using a belay device to capture progress on a climbing haul system, often used for crevasse rescue, has become more complicated due to modern ropes. The thinner diameter of these ropes means tighter wraps on the prusik, which - in turn - means those wraps are small enough to get stuck in the device and break the capture system.
