A tool used to determine the balance point of a golf club, effectively measuring how heavy the club head feels during a swing. This measurement, typically expressed as a letter-and-number combination (e.g., D2, C9), helps golfers match their equipment to their physical capabilities and swing characteristics. For instance, a golfer with a faster swing speed might benefit from a higher measurement, while a slower swing might require a lower one.
Matching equipment to individual swing characteristics is crucial for maximizing performance and minimizing the risk of injury. Historically, determining this balance was a more subjective process, relying heavily on feel and experience. The development of this analytical tool provided a more objective and precise method, allowing for greater customization and fitting accuracy. This has led to improvements in club design and a deeper understanding of the biomechanics of the golf swing.
