The Stimpmeter is a modified version of a device designed by Edward Stimpson (in 1978) who came up with his idea after watching players struggle with excessively fast greens. This new version allows for greater flexibility in measuring green speed, especially on undulating surfaces that have smaller areas of level turf, a necessity for measuring green speed. 36" (91 cm) long, the Stimpmeter features a lengthwise groove, with a notch about 30" from the tapered end. The ball sits in this notch at the starting position, lying flat on the ground; when the user lifts the other end of the Stimpmeter to an angle of about 22°, gravity releases the ball from the notch. The ball rolls down the Stimpmeter and along the green, and the average distance traveled by the ball after a number of attempts is the figure that has come to represent the speed of the green.
