Speed Gun

Invented in 1992 for a sports-crazy nation by innovator and engineer Henri Johnson, the speed gun was unveiled in 1999 at the Cricket World Cup. Commonly called the EDH Speed Ball, it is used to measure the speed and angle of fast-flying balls, especially those thrown from the bowler’s hand in cricket, or served in tennis matches.
