2-Line function
The 2-line function is especially interesting for training groups of tennis players. When 2 groups
of tennis players are on the tennis court, each group gets one ball every time at the same place.
Without the 2-line function, the ball will be shot on different places and also in between the two
groups. With the 2-line function the trainer could exactly say the group1 plays forehands and
group2 plays backhands. Therefore this function is very popular among tennis trainers who want
to train 2 groups of players.
