Abstract

Abstract The invention is concerned with a device for practicing and improving a golf swing. Its most advantageously used when practicing with a wood or iron rather than with a putter. The device features two walls with an alley in between them, the alley having an artificial turf-like material thereon. The separation of the walls is adjustable so that the walls can be brought closer together as the golfer''s swing improves. At least the wall closest to the golfer may be rotated to form different angles with the artificial turf. The angle can be adjusted to suit the size of the golfer and the particular golf club being used, and also to enable the golfer to establish a standard distance between himself and the ball. The bottom surface of the device includes two rotatably attached spikes for anchoring the device in the ground. The spikes may be rotated relative the bottom surface and fitted into depressions which include constrictions for holding the spikes in storage positions.
