Abstract:
A sports swing aid is adapted for being mounted on a shaft of a sports implement, for example a golf club. The sports swing aid has a conical shaped mounting block with a channel formed to straddle the shaft. A rotor is removably assembled on the mounting block. The rotor has an array of vanes on the periphery thereof to cause the rotor to rotate when the sports implement is moved through the air. An eccentric weight is provided to impart a vibration as the rotor rotates and thus generate feedback to the sports player indicative of the smoothness and speed of the swing.
