Abstract:

A base with a referenced concave surface and a movable indicator form a putting aid which indicates direction and amount of slope on a golf green. Diametrically opposed sighting rods provide convenient and accurate visual alignment while the putting aid is situated down upon the golf green. Arrowheaded linear, transverse linear and concentric circular indicia located upon the concave surface serve as reference markings. A first method of operation includes facilitating the training of a golfer to putt a golf ball into a golf hole by aligning the putting aid between the golf ball and the golf hole such that the sighting rods and arrow indicium are aligned with an imaginary direct line between the golf club and the golf hole. A second method includes facilitating the training of a golfer to correctly perceive slope by placing the base upon the ground at a test location while rotating the putting aid to align the sighting rods and arrow indicium with a perceived downhill direction before the movable indicator is released to move about the concave surface and indicate actual direction and amount of slope. A third method includes facilitating the mapping of slopes on a sloped green by observing relationships between the movable indicator, the reference indicia, and physical reference objects around the green.
