Patent ID: 6890273

Claim:
A offset determining system, upon a putting green having a topography of varying slope, for use by a golfer in hitting a golf ball from a maximum position toward a hole having a hole center, to suggest to the golfer a redirected putt line that varies by an offset distance transverse to and at the hole from a direct putt line which extends between the ball and the hole center, comprising: a target having a target face having a target line extending thereon, the target for positioning adjacent the hole with the target line aligned with the direct putt line; and a measurement device having a housing having a top, a bottom, a pair of transverse sides, a rear, and a front, and positioning indicia for aligning the rear transverse to the direct putt line, the measurement device having a transverse inclinometer extending longitudinally between the transverse sides and substantially parallel to the bottom, the measurement device having a rangefinder for determining distance between the front and the target, the measurement device having a control unit for determining the offset distance from at least two measurement sets each having a distance to the target and a slope at that distance and a display for providing the offset distance to the user, wherein one of the measurement sets is acquired upon placing the measurement device at the maximum position, and another of the measurement sets acquired upon placing the measurement device further toward the hole along the direct putt line.
