A tracking device for a golf club, which requires no electrical power source, is comprised of a body of fiberoptic material which is affixed to an exterior surface of the golf club. The fiberoptic material gathers ambient light along its length, and directs that light, through internal reflection, so as to cause it to exit at an end. The illumination provides a bright spot on the head of the golf club which traces the path of the moving club. The fiberoptic material may include a fluorescent dopant which absorbs light of short wavelength and converts that absorbed light to emitted light of a longer wavelength. Use of the fluorescent dopant enhances the intensity of the light emitted from the device.
