A golf practice device has a body that includes at least one battery, a display generator that presents a visual or audio display when energized by the battery, and a sensor switch that closes an electrical circuit that connects the battery to the display generator when the device is struck by a golf ball. In one embodiment, the bottom of the body is attached to a pin which is inserted into a golf green. In another embodiment, the bottom of the body is made of a material having many small hooks on it so that the body will grasp onto a fabric, such as a carpet. When a golf ball strikes the golf practice device it presents a visual or audio display to the golfer.
