Siboasi S4015 Tennis Ball Machine

Internal Oscillator- SIBOASI tennis ball machine uses counter rotating wheels to propel the balls. It is the most effective method of ball propulsion allowing the machine to remain silent and effectively produce topspin and slice. The wheels are black to help disguise their location inside the machine, helping to make each shot almost unpredictable. To make your training more effective, unpredictability of shot is what you shouldn’t ignore.

Portability- S4015 has oversized wheels and telescopic handle, and with a reversible hopper. You can put it into the back of your car and take it easily like a luggage case.

Extreme Spin- These machines have “extreme grip” throwing wheels which can create very high levels of topspin & slice. When set at the maximum level, the difficulty of the spin is so high that if you can master it, you will have no trouble dealing with your opponent’s in real match play. Of course you can always set the spin to much easier levels for more realistic practice.

Horizontal & Vertical Oscillation- With this horizontal and vertical osillation funtions and adjustable serving distance (speed), the machine is able to feed balls to any spot on the half court. You can practice your move and any technique you want with the machine (forehand, backhand, volley etc). Also you can do a random drill under which the balls maybe land anywhere on the half court.
