Many golfers fail to succeed because they do not aim accurately enough when putting. We thus developed the HPS 30 Aim Aid Set for practice and training purposes. The marker template included in the set can be affixed to an accurate precision sight line centered on the ball diameter within a matter of seconds. You can then use the alignment aid to verify whether you are pointing in the right direction and your aim is true. The set also comes with a small KRAMSKI aim guide.
