ABSTRACT:
A measuring device for use with hi-jump standards to aid jumpers in determining their in-run starting points approaching the high jump in practice or in competition. The device includes a base member having a 0 to 180 degree scale, whose end points are parallel with the cross-bar, together with a swivable arm that can be set at the desired angle. The arm includes a measuring tape attachment point so that once the angle is set, a measuring tape can be used to determine the exact starting point. The device can be integrally formed with a standard or be separately attachable to a standard.
