Stimpmeter

A stimpmeter measures the green speed and comprises an extruded aluminum bar with a V-shaped groove extending along its entire length. It has a precision milled ball-release notch 30" from the tapered end that rests on the ground. The underneath is milled away to reduce bounce when the ball hits the green. The V-shaped groove is angled 145 degrees to support a golf ball at two points ½" apart. A ball rolling down the groove has a slight consistent overspin which has no adverse effect on the measurements. The ball-release notch functions when the Stimpmeter is raised to an angle of approximately 20 degrees. This feature ensures that the ball speed will always be the same when it hits the green.
