Claim Text:
1. A method of detecting head movement during a golf swing, the method comprising the steps of: providing first and second separated sensor devices, each including an accelerometer, a processor, and a communications module; the first sensor device is characterized as a head monitor sensor and is configured to monitor movement of a head of a golfer, and the second sensor device is characterized as a club monitor sensor and is configured to monitor movement of a golf club; during a golf swing, the accelerometer in the club monitor sensor device measuring forces in three orthogonal directions and generating swing data in response thereto; the processor in the club monitor sensor device detecting an impact time in the swing data; the accelerometer in the head monitor sensor device measuring forces in three orthogonal directions and generating head data in response thereto; the processor in the head monitor sensor device processing the head data around the impact time to detect head movement; and the processor in the head monitor sensor device issuing an alert in response to the head movement exceeding a threshold.
