Abstract
A golf trainer includes magnetic sensors for detecting the passage of a golf club head and is provided with a device for electronically measuring the speed of the club. The carry of the ball is also calculated, except when the club selected for use is a putter, from data regarding the club selected and the characteristics of the speed of this club versus the carry of the ball.
