ABSTRACT:
An indoor-outdoor golf practice device for use with all golf club woods, irons and wedges wherein a lightweight practice golf ball is attached with a selectable length cord to a single fold-over, flexible flap. The flap contains one or more small calibration weights at its opening end and covers distance-marker scales, with each scale corresponding to a particular range to be measured. The kinetic energy at a particular point in the flight trajectory of the well-hit light-weight properly positioned practice ball, which simulates a roughly 250 yard drive is sufficient to fully open the fold-over flap with a 10 foot tether cord, thus exposing the high range full scale markers up to 250 yards. Similarly, the poorly hit practice ball contains less kinetic energy at the same selected point from the flap in its flight trajectory, and only partially opens the flap which exposes lower yardage markers indicating a low quality drive for short iron and wedge strokes, a shorter effective length of tether cord is used to utilize an equivalent power point on shorter ball flight trajectories, making possible multiscale operation with improvement in scale readout resolution on low power ball flight trajectories.
