Length measurement of ski jumps - by marking landing point with marker e.g. of cloth or paper, carried by jumper

摘要

The ski jumper picks up a marker at the take-off platform and carries it during the jump. The marker identifies the point to be measured at the landing point at the height of the binding. The marker is in the form of paper, cloth or other material which is forced into the snow on landing. Alternatively an ink marker can cause a coloured spot on the snow at the landing point. USE/ADVANTAGE - For measuring length of ski jump. Accurate measurement.
