All Silent Partner Series ball machines feature a ball acceleration system that is among the most powerful on the market. Two independently driven and electronically controlled accelerating wheels allow the ball to be ejected at speeds of up to 150 km/h while simultaneously influencing ball spin over a wide range. A special, durable coating prevents the balls from slipping through without regular roughening of the accelerator wheels.
The protected control panel is located on the side of the ball machine. From there, all functions of the ball machine can be controlled centrally.
Ball speed and spin can be adjusted independently of each other. The electronics independently control the accelerator wheels. The large control range covers ball speeds from 25 km/h and covers the range from extreme back-spin to drive and rapid top spin.
The interval between two ball throws can be adjusted down to 1 second, for example, in order to be able to practice balls in quick succession at net.
With only 18kg the LITE is exceptionally light for its class and therefore easy to handle. But even the top model, the PRO, weighs only slightly more at 23kg.

Silent Partner STAR and PRO also feature a programmable oscillating mode. In this mode, the ball machine alternately plays two (three in case of the PRO) user-defined throwing targets parallel to the baseline and according to the settings you have selected (ejection speed, spin, ejection angle and ball frequency).
Silent Partner LITE and STAR tennis ball machines provide random oscillation. The balls are shot "quasi randomly" over an area parallel to the baseline right-left. The Silent Partner STAR offers oscillation in two variants (slow or fast). The Silent Partner PRO's random oscillation mechanism also offers a 3D mode (see picture).
All Silent Partner ball machines are equipped with two solid wheels and an telescopic handle, which allows you to easily move the machine (see photo).
The machine has a capacity of 200 balls.
All machines are equipped for battery operation as standard. Already the Silent Partner LITE contains a maintenance-free lead-fleece battery with a capacity of 10Ah. This allows up to 3 hours of playing without recharging in between.
An optional power supply unit (Silent Partner PS) is available for the ball machines STAR and PRO for connecting the machines to the 230V mains (see picture). This high-performance power supply unit weighs approx. 5 kg. The robust aluminium case resists even the toughest conditions.
