The Aiming Golf Setup and Alignment device is designed to help with one of the most common golf swing problems: poor alignment.
To use it, you stand behind the ball, facing the target. Clicking on the device registers the alignment. Then, as you set up behind the ball, The Aiming corrects your alignment with audible feedback.
The Aiming is not legal for use on a course, but if you deploy it on the range and for practice rounds, you just might find your alignment improving.
