Abstract
A swing training device usable by a golfer comprises an elongated lightweight shaft adapted to be swung by a golfer to produce either a desirable accelerated or insufficiently accelerated swing, corresponding respectively to a desirably or insufficiently accelerated swing of a golf club, relative to a golf ball; and sound producing structure associated with the shaft to produce a distinctive audible sound when the shaft is swung so as to define a desirably accelerated swing.
