Abstract
A green speed measuring apparatus is in the form of a longitudinal bar having inwardly inclined, longitudinally parallel surfaces on each side, to define a trough or ramp for rolling of a golf ball thereon. A standard distance of one notch on a first side is provided. In addition, on the second or obverse side, one or two additional notches are provided in the ramp thereon at different distances from the ends of the bar. Each notch is associated with a scaling factor to obtain the speed of a level green. The longest notch from one end of the bar may be marked with a scaling factor of 1.00 as the notch is located at 29.4 inches from the end; the middle notch, if located at ½ the distance of the longest notch is marked with a scaling factor of 1.83; and the shortest notch, if located at a distance of ¼ the distance of the longest notch from an end of the bar is marked with a scaling factor of 3.34. The preferred embodiment provides only a second notch on the lower side and a scaling factor of 2, and that notch is located at a distance of 13.625 inches from the end of the ramp.
