<p>A method and apparatus for practising shooting. In the invention, data on the direction and velocity of the wind are measured by means of wind sensors (1a - 1n) and the wind data in question is led through a central unit (2) to a display device. The display device shows the effect of the wind conditions on the trajectory of a bullet, when the marksman can practise reading the wind conditions with the aid of wind vanes.</p> |
