*** Recommended check points ***
We have been receiving valuable feedback at the prototyping phase, and would like to introduce some basic check points. Please check it out. Also we appreciate further better feedback or advice regarding usage of it.

1. A case where shooting from right back
On a screen of address, Draw a line from your shoulder to a ball and another line from your belly button to a ball, and draw a circle at your head position.
* Check point: Check if a club head doesn’t go over the two lines. Also check if your head moves from the circle (It is ok that your head goes down at the time of impact).

2. A case where shooting from front
Vertically draw two lines from a center position of your both legs to ground, and draw a circle at your head and two circles at both knees.
* Check point: Check if your head, knee and body doesn’t shift too far to the right (to the left on the screen) when the club is at the top position. Also check that left elbow is not flexed at the time of impact.

This is just an example. We wish you will make a record for your best score by reading lesson books and golf magazines, or on advices from lesson professionals and other advanced players. We appreciate that you would have had interest in “EasySwingChecker”.
