A Stimp-meter is a device used to measure the speed of a putting green. The Stimp-meter distance, or Stimp-meter reading, is the distance in feet that a golf ball rolls when launched from a Stimp-meter on a flat surface. It is an indicator of the speed of the green and can be used to compare the speed of greens between different golf courses or between different greens on the same course. When using a Stimp-meter, a golfer places the device on a flat surface and releases a golf ball from the end of the Stimp-meter. The ball rolls down a ramp and onto the putting green, where it continues to roll until it comes to a stop. The distance the ball travels is then measured, and this distance is the Stimp-meter distance.
