There are many training aids, but only a few that are as easy to use as the "Pocket Pro", always with you and flexible for your entire game.
Many of my students keep asking me about alignment, swing plane training, and most importantly, proper ball position. This is exactly what you can now independently control, practice or improve with the Pocket Pro.
As the national coach, I can only say that with the Pocket Pro, amateurs get what makes a top player: solid basics!
Also a great gift for the Christmas season! Have fun with it!
