One of the hardest things to repeat even for a tour player is club face alignment. Face is what sends the tour player home on Friday. Wrist alignments are what controls the face. The downswing takes only around 1/4 second, so you really don’t have time to fix improper wrist alignment. That is why it is so important to get the wrist alignments correct early. Using Hackmotion Wrist Sensor’s data you can quickly analyze wrist alignments and fix them.
