PlayerMD™ GM (Gear Management), ensures proper helmet fit and performance of safety equipment. PlayerMD™ GM monitors helmet fit using a combination of sensors packs with one in a skull cap and one mounted to the helmet. This allows impact data to be compared between the point-of-contact (i.e. helmet) and the head itself to ensure proper helmet fit and overall performance throughout the season. PlayerMD™ GM monitors shoulder pads by fitting one sensor pack in the shoulder pad and another underneath the pads to measure overall pad absorption and performance. Each athlete's performance history is tracked throughout their lifetime across multiple sporting or active pursuits allowing a holistic view of the athlete.
