Abstract: A laser light-emitting golf ball having a laser emitter for emitting coherent light in an outwardly extending direction from the ball, a power module, and an activation switch. An illuminating tilt-sensing golf ball having an illuminating component for emitting light at a predetermined frequency, a tilt sensor coupled to a control module, and upon the control module receiving a tilt detection signal, the control module being adapted to control the illuminating component to emit light at a second predetermined frequency if the tilt ball tilts more than a predetermined angle. The ball can also include a motion sensor, recording medium and transceiver for storing and transmitting motion sensor readings.
