Abstract: A swing alignment device (1) for assisting or training a golfer to swing with the correct golf swing, the device comprising: a rod-like member (2); and a mounting member (3) for mounting to a shaft (5) of a golf club (6), the mounting member providing a support means (7) which supports the rod-like member on the mounting member such that the rod-like member (2) extends substantially parallel to the shaft and permits the rod-like member to slide relative to the support means (7). The mounting member (3) is suitably adapted for mounting to the grip portion (4) on the shaft of the golf club (6) and includes a grip engagement formation (10) for placing against the grip portion of the shaft (5). The support means for the rod-like member comprise at least one sleeve through which the rod-like member (2) passes, whereby the rod-like member is supported with its longitudinal axis closely laterally spaced from the axis of the golf club shaft (5).
