<p>An athletic implement, having a self-contained, built-in system for measuring impact between the implement and a struck object and for displaying the distance traveled by the struck object is disclosed. In the disclosed preferred embodiment, the athletic implement comprises a golf club having an acceleration sensor mounted in the club head for detecting the deceleration shock pulse generated upon striking a golf ball with the club head. The sensor transmits an analog electrical signal proportional to the peak amplitude of the shock pulse to battery-powered electronic circuits mounted in the club handle. The electronic circuits convert the analog signal to digital signals proportional to range or distance traveled by the ball and transmits the same to a decoder/driver which drives a digital display such as a LCD or LED display mounted in the end of the club handle. After the ball is struck with the club, a display "on" switch is activated by pressure applied to a predetermined location on the handle to display range numerically in yards on the digital display.</p> |
