A tool used to determine the balance point of a golf club, expressed in letter/number combinations (e.g., D2, C9). This measurement reflects how heavy the club head feels during the swing, distinct from its overall weight. For example, two clubs of identical weight can have different balance points, leading to significantly different swing sensations.
Proper club balance is crucial for consistent ball striking, tempo, and overall performance. Historically, matching swing weights across a set of clubs was done by feel. Modern tools provide precise measurements, allowing for finer adjustments and improved club fitting. This facilitates optimized performance and helps golfers achieve greater control and distance.
