basically generate snow in the same way as fan guns. A greater height is required, however, to crystallize the snowflakes because they lack the propeller, or turbine, fitted in the fan guns. Snow lances therefore have a lower projection range and greater wind sensitivity but they are more accurate in terms of where the snow lands. The quantity of snow produced by a lance is similar to that of a small fan gun. Ideal fields of application are, for instance, narrow slope sections without particular exposure to wind, connecting pistes or ski trails.
