<p>The present invention relates to a putting practice device for sensing the swing trajectory of the putter during a putting practice and informing the golfer through five senses, particularly tactile sense, thereby enabling the golfer to make the same swing trajectory. The putting practice device comprises: a body; a plurality of sensor units installed on a side surface of the body at a predetermined interval; a sensor unit selection means for selectively activating at least one of the sensor units; a controller for receiving and outputting a signal, when the signal is sensed by at least one sensor unit selected by the sensor unit selection means; and a wireless reception vibration means provided on one side of the putter to receive a control signal outputted through the controller and generate vibration, thereby informing the putting practicing person through the tactile sense.</p> |
