Abstract
A calculating unit of a swing analyzer calculates, assuming that a golf club is in a uniform circular motion about a virtual center of rotation O during a swing, a virtual speed Vh at a central point R of a golf club head, based on a distance between first and second acceleration sensors, a distance between the first acceleration sensor and the central point R of a golf club head and outputs from the first and second acceleration sensors, and calculates the speed of central point R of a golf club head utilizing the virtual speed Vh.
