Line-M-Up Pro

This playing and training aid provides multiple marking options to improve aim, stroke and green reading ability.

Use your preferred marking to establish your aim-line, once confident of the line, you're free to concentrate on stroke and speed. When a good stroke is made, the markings on the ball appear straight with a pure roll. When poorly struck, the markings will show a wobble. When a pure stroke, with proper speed misses the hole, your green read was wrong. Once you've isolated your mistakes, you can make adjustments to improve your green reading skill.
