The tool used for this purpose is called a Stimp Meter. It’s a simple yet crucial device that helps maintain consistency in green speeds across a golf course.

The Origin of the Stimp Meter

The Stimp Meter, or “Stimpmeter,” was invented in 1935 by Edward S. Stimpson, a former amateur golf champion from Massachusetts. Stimpson created the device after experiencing frustrations with inconsistent green speeds during a tournament.

He wanted a way to measure and compare the speed of greens, leading to the development of a tool that is now a standard in golf course maintenance.

Initially, the Stimp Meter was a simple, handmade device. It wasn’t until 1976, when the USGA (United States Golf Association) adopted the tool, that it became widely used in the golf world.

Today, the Stimp Meter is an essential tool for golf course superintendents and tournament organisers to ensure fair play.

How a Stimp Meter Works

A Stimp Meter is a straightforward tool, typically made of metal or plastic, about 36 inches long with a V-shaped groove running along its length.

The process of using a Stimp Meter is also simple:

1. Place the Stimp Meter: Position the Stimp Meter on a flat section of the green. The bottom end should rest on the green, with the other end held at an angle.
2. Release the Ball: A golf ball is placed in the groove at the top of the Stimp Meter. The tool is then slowly raised to an angle of about 20 degrees. At this angle, gravity causes the ball to roll down the groove and onto the green.
3. Measure the Distance: The distance the ball rolls on the green is then measured in feet. This distance is known as the “Stimp reading.” The longer the ball rolls, the faster the green is.

Typically, the process is repeated in opposite directions to account for any slope or grain, and the average of these distances provides the green speed.

The Stimp reading gives golfers and course officials a clear idea of how fast or slow the greens are playing.

Understanding Green Speeds

The speed of a green is crucial because it affects how much a ball will break and how much force is needed for a putt.

Stimp readings help ensure that greens are consistent throughout a course or tournament, creating a fair and predictable playing environment.

• Slow Greens: A Stimp reading of around 7 to 8 feet is considered slow. On slow greens, players need to hit the ball harder to reach the hole.
• Medium Greens: A reading of 8 to 10 feet indicates medium speed greens. These are typical for many golf courses and provide a balance between control and power.
• Fast Greens: Readings above 10 feet are considered fast. These greens require a delicate touch, as the ball will travel further with less effort.

Courses hosting major tournaments, such as

The Masters, often have green speeds in the 12 to 14 feet range, demanding precision and skill from the players.

Why the Stimp Meter will be used in golf for years to come

The Stimp Meter is not just a technical tool; it’s essential for maintaining the integrity of the game.

By measuring green speeds, course superintendents can make adjustments to ensure that all greens on a course play consistently.

This consistency is especially important during tournaments, where even slight variations in green speed can affect the outcome of a match.

For golfers, understanding green speed is critical to adjusting their putting strategy. A good grasp of how fast or slow the greens are can lead to better decision-making and, ultimately, lower scores.
