· A Stimpmeter works on the principle of applying a measured force on the golf ball and then measuring the distance the ball traveled. The ball travels at a known velocity every time on the ramp. Once it rolls on the putting green, the distance traveled by the ball is considered the speed of the putting green or it’s Stimp Rating.

The Stimpmeter is a simple, accurate device manufac- tured by the USGA that allows one to make a standard measurement of, and place a numerical figure on, the speed of a putting green. It does so by measuring ball roll distance.

What is the use of a stimpmeter in golf?

Have you ever felt that on particular days and on particular greens, you simply can’t putt? Well, there’s nothing wrong with that because greens change their speed very frequently.

Doesn't the ball release from a regulation Stimpmeter at 35 degrees (when performing an accurate reading)? What about this device differentiates it from a regulation Stimp in allowing the user to get an accurate reading at a 20 degree release? Is there a formula associates with the difference? Thanks.

Feedback

I believe a regulation Stimpmeter is raised above the ground at a 20 degree angle, 35 degrees would make the ball jump off the ground as soon as it is released from the Stimpmeter, causing inaccurate readings.

Feedback

I assumed you have made one yourself?! Please post pics! A member where I worked showed me how they test the speed of greens. Being just my 5th year in golf, it was interesting to know it is a very simple process.

The other side of the coin is that unless you are a PGA Professional or GCSSA golf course superintendent you can't buy a Stimpmeter from the USGA.
