The GS3 Ball has been an absolute game changer for Atlanta Athletic Club.  We are going to utilize every bit of it: we want the speed, the trueness, the smoothness, the firmness.  We go out every day we have play, 6 days a week, capturing as much data as we can. The GS3 Ball and DEACON platform has totally changed our ability to monitor the day-to-day conditions, pick up the trends, and make quicker adjustments.  It’s an amazing tool.
