Abstract
An apparatus for practicing golf putting strokes. The apparatus provides a generally direct correlation of the linear distance that a ball will travel and comprises a synthetic putting surface of sufficient roughness to achieve generally direct correlation of the linear distance of travel, and a spirally arranged wall member defining a spiral track along which a ball will roll; display numerals, corresponding to the linear distance that the ball rolls, may be provided on the spiral. The apparatus may be provided with a target simulating a portion of a regulation golf hole, riser members which vary the incline of the spiral track to simulate uphill or downhill putts (or combinations thereof), a ball return device which rotates above the spiral wall and sweeps the spiral track of balls which are resting thereon, and/or at least one removable obstacle.
