Stimpmeter Golf Green Speed. Each side has a notch to place the golf ball and measure the roll distance and therefore the speed of the green. A stimpmeter helps measure the speed of the greens but only if used correctly.

It has proven to be an invaluable asset to the game of golf both for daily play and championship preparations and a helpful management tool for the golf course superintendent but it is not intended for course comparisons. This ramp style device has a notch and the ball is pulled out of that notch by gravity when the device is slowly raised to an angle of about 20 rolling onto the green at a repeatable velocity of 600 feet per second. How many feet it then rolls on a flat putting green is the green speed.
Of a putting green is a numerical value that represents how fast the golf ball rolls on the putting surface.
Not all greens have a flat section which is suitable for this test so you may. 20180405 Being able to test and then adjust the green speed is a way of ensuring the greens are playable everyday. Measurements are taken on a relatively flat part of the golf putting green. 20180215 As the bar is raised and the angle increases to approximately 22 degrees gravity naturally takes the ball down the Stimpmeter at a speed of 6 feet per second.
