Henri Johnson is an engineer who used his background in radar to develop the technology that measures the speed and direction of tennis, cricket and golf balls during play. This innovative technology is used in tournaments around the world and provides fascinating insights into the playing techniques of famous sportspeople.

Henri Johnson's ball-tracking products have been used in the PGA and Davis Cup events.

Henri Johnson didn't picture himself as a future inventor. A South African engineer, Henri Johnson was more concerned with engineering, initially working on sonar and radar projects.

But a drive to be a part of something more exciting saw him applying his mind more creatively. As a South African inventor, Henri Johnson was responsible for developing the sports tracking technology used around the world today.

Henri Johnson's love for engineering began as a young child and peaked with him studying engineering after school. His initial focus was on sonar projects, which he undertook on behalf of the South African Navy.

He ventured into the world of radar and enjoyed great success when he developed the radar technology that could measure the velocity and ballistics of projectiles in flight. This technology would go on to be used in military units around the world.

Johnson started the engineering firm, Electronic Development House (EDH) and serviced a growing clientele from a broad range of backgrounds. But he felt there was still more he could do − something bigger and more exciting based on his previous engineering work.

He began by investigating the everyday, commercial use of his military projectile application and discovered that similar technology could be used to measure the speed of balls played during sport.

First he looked at the cricket pitch and designed the EDH SpeedBall, which measured the speed at which the ball left the bowler's hand. Then he applied similar technology to the tennis court and invented the RaquetRadar, which measured the speed of a player's service.

Finally he turned his attention to the golf course and developed the FlightScope. A comprehensive 3D tracker, the FlightScope is able to follow the trajectory of golf balls, providing information as to the speed, direction and angle of the ball as well as critical feedback to the golfer.

EDH also serves other sporting disciplines and continues to service the military market.
