Today we still hit each brand of ball with the mechanical golfer, but instead of hitting the balls outside onto the range, we hit them into a net and measure their launch conditions off the clubhead velocity, direction, and spin.
The Indoor Test Range is a foot long "tunnel" through which the balls are launched using a golf ball launcher that is similar to a pitching machine. This information is used in a sophisticated computer program to accurately calculate driving distance of an actual drive. This "virtual" distance data is highly repeatable and not subject to weather variations.
Each ball is carefully measured for size and weight. The balls are then tested to determine their initial velocity. All of this is carried out in a climate- controlled laboratory to make certain that all balls are evaluated at the same temperature and humidity. All components of a golf club are subject to evaluation by the USGA to determine a club's conformance. Heads, grips, and shafts all have specific specifications that must be met. Some of these are objective; like the width and depth of grooves.
And like the ball, the tools range from simple devices such as a ruler, to complex test instruments such as contour readers for measuring groove sizes, and to a USGA-developed pendulum test to determine the flexibility of the golf club face.
Some of the standards for golf clubs and other golf equipment, such as tees and gloves are less objective and require a detailed examination of their intended use and consideration of past precedent to make a determination of their conformance. Nevertheless, conformance determinations are made on more than two thousand clubs, club components, tees, gloves, etc.
The Technical Staff constantly monitors the game and how equipment advances are affecting its evolution. This is accomplished by closely studying the performance statistics; conducting scientific studies of professional golfers and recreational golfers; and through detailed research about why and how golf equipment works the way it does.

A statistical analysis of over scores of golfers handicaps 0 - The scores were used to simulate over matches. A statistical analysis of those matches ensued. Do the holes on your course have a fair handicap difficulty ranking? Are there some holes you rarely win?
Find out how to calculate the actual difficulty of your holes. Check out the Hole Difficulty Ranking Calculator. Here is a snipit of the report: What is the Longest Golf Ball? Often golf ball manufacturers advertise that they make the longest ball.
Some might even provide testing results that compare their ball's distance to their competitors'. They cite statistics that "prove" their ball is the longest. A famous saying about statistics is "there are lies, damn lies and then there are statistics.
Then again, other ball manufacturers don't make such comparisons. There is a reason for which I'll reveal in this study Pro V1 was not hit in the study but the conclusions can be applied to all golf balls. This study involves a statistical analysis of how long various golf balls travel when hit by a driver. Most of the data was collected in but golf ball construction has not changed significantly since then.
Hot Stix used a cc titanium driver, 9. We tested the driver at four clubhead speeds 60, 80, and mph and the 6-iron at three speeds 60, 80 and mph. Plots show launch and spin values across the designated swing speeds. Your swing may produce different results be sure to conduct your own on-course evaluation.
Finding On average, the premium three-piece ball launches lower blue bar and spins roughly rpm more off the driver. The three-piece ball also launches lower with a 6-iron green bar and produces rpm more backspin.
Differences between ball types are likely due to the two-piece ball sliding up the face prior to fully engaging it higher launch with less spin.
Senior Vice President of Titleist Golf Ball R&D Bill Morgan and Director of Product Implementation Matt Hogge give us a behind-the-scenes look at the process and people behind the development of the new Pro V1 and Pro V1 x golf balls.
Today, the golf ball market is worth around $ million in annual sales, with over million golf balls being manufactured and shipped every year. Currently, balls are made in two or three parts. A two-piece ball is made of rubber and plastic, and is mostly used by the casual golfer.
All properly struck golf shots are hit with backspin, making the golf ball fly just as the wings provide lift to an airplane. Research. Equipment conformance testing isn't all that goes on at the USGA Research and Test Center. The Technical Staff constantly monitors the game and how equipment advances are affecting its evolution. Golf Ball Technique Posted on February 20, We call this technique the million dollar self help technique because it so valuable in helping a number of conditions like .
Ball testing: Start with shots around the green, and work back until you can't see differences. Ball testing: Start with shots around the green, and work back until you can't see differences. Playing the right golf ball is just as important as--and possibly even more than--being fit for any club in your bag. What is the Longest Golf Ball? Often golf ball manufacturers advertise that they make the longest ball. Some might even provide testing results that compare their ball's distance to their competitors'.
