What is random oscillation?
Random oscillation is where the tennis ball machine replicates a match situation by shooting balls randomly around the court. Rather than groove a particular shot, this allows a player to focus on footwork, fitness and practice shots in a more realistic environment. Most machines with oscillation are capable of faning from side to side which works both your forehand and backhand. Unfortunately they do not vary the depth of the ball (eg, if your machine is set to hit the baseline, it will fan from side to side always hitting the baseline). However the very top machines are capable of dropping in short balls and deep balls as well. This is a feature of the Lobster Elite II, Lobster Elite III & Tennis Tutor Player Model which are the only machines in their price range that can claim this.
