<p>A self-adhesive indicator which adheres to a golf club face to provide an indication of the point of impact of the golf ball on the club face is provided. It consists of a sandwich of various layers - a layer of pressure-sensitive adhesive on the bottom, followed by a layer of energy-absorbing elastomeric material on which is provided a film of a thermochromic material such as a temperature sensitive liquid crystal, followed by a top layer of clear high impact plastic. Unlike the prior art golf aids, the device is simple and durable so that it can be used repetitively.</p> |
