The Tennis Tutor with wireless remote control lets you start and stop ball delivery, and control the side-to-side position of the ball throws. It features counter-rotating wheel operation and an electronic control panel for fingertip control of the ball speed, trajectory, and ball feed rate. Tennis Tutor also features an exclusive anti-jam ball feeding mechanism, and a 10-second start-up time delay to give you time to get to your side of the net.
