发明名称 GOLF CLUB IMPACT RECORDING SYSTEM
摘要 <p>A system is disclosed for recording the location on a golf club (25) where the club head (20) impacts a golf ball. A recording medium (10) is attachable to the club head (20) prior to swinging the golf club (25) and is removable from the club head (20) after one or more impacts against the golf ball. One surface of the recording medium (10) is coated with a releasable adhesive substance (10) to permit temporary attachment of the recording medium (10) to the club head (20). A backing material (80) covers the releasable adhesive substance (104) prior to utilization of the recording medium (10) on the club head (20) to prevent the recording medium (10) from adhering to unintended objects.</p>
