Battery-operated, rechargeable units feature electronic ball speed and interval adjustment, manual trajectory control, and built-in full-court oscillator for random delivery of shots. Tennis Tutor™ Plus also offers backspin and an anti-jam ball-feeder. AC Power Adapter sold separately.
Tennis Tutor features an electronic control panel which gives you fingertip control of ball speed, trajectory, and ball feed rate (the time interval between ball throws). Ball speed ranges from a gentle toss for children to world-class speed. Ball trajectory can be set anywhere between groundstroke and lob, while ball feed rate adjusts anywhere from 1-1/2 to 10 seconds. You can set Tennis Tutor to repeat shots you need to practice, or to oscillate and direct shots randomly across the court. 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.
Tennis Tutor is truly portable, measuring only 12 inches tall when the ball hopper is folded down for transport. And with the towing handle extended, it tows just like luggage. When you get to the court, the ball hopper opens in seconds to hold 150 balls, which is more than two standard pick-up baskets full of balls. Tennis Tutor comes standard with a built-in heavy duty rechargeable battery that can deliver up to six hours of playing time, so there's little need for extra batteries. Tennis Tutor has a built-in battery charge indicator, and it even politely beeps when there is only one-half hour of battery charge left. And of course, Tennis Tutor comes complete with a Smart Battery Charger that fully charges the battery overnight.
