A golf swing practice comprises a body for attachment to a golf club at the upper end of the club with a second end fitted to the club shaft below the grip. There are a pair of first laser light sources which are directed downwardly and outwardly so as to create diverging beams of light which pass by the front and rear faces of the club head in a plane perpendicular thereto. Securement of the body at the upper end of the golf club is by a pin axially inserted into the end of the club, and by a geared clamp positioned below the grip portion of the golf club so as to be symmetrical about the longitudinal axis thereof. A practice mat has two zones for different stroke practice, and a ball can be struck from it. The speed and direction of a golf club may optionally be determined.
