Abstract: Various embodiments of a golf device for use on a putting surface are provided. In one aspect, a golf device for use on a putting surface is provided that includes a ball that has a center and a first outer diameter. First and second annular members are coupled to the ball in substantially parallel spaced-apart relation. The spacing of the first and second annular members defines a spherical zone of the ball that projects radially outwardly from the center beyond the outer peripheral surfaces of the first and second annular members. The first and second diameters of the first and second annular members are sized so that a first portion of the first outer peripheral surface and a second portion of the second outer peripheral surface are positioned substantially at the putting surface. The device provides rapid tactile and visual feedback of a misstroke.
