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.
