The Shotmaker® is the "Top of the Line" ball machine from Sports Tutor. Its power and versatility will challenge players at any level, including professionals. The Shotmaker® provides the wealth of features you would expect of a top-of-the-line ball machine including 300 ball capacity, speed ranges from 10 MPH to 95 MPH and adjustable spin (from heavy underspin to flat to heavy topspin). The Shotmaker allows for adjustable trajectory from groundstrokes to lobs and includes interval control to adjust the time between shots from one second to six seconds. The Shotmaker also offers its lucky owners long term durability. The Shotmaker's case is made of high-impact injection-molded plastic and powder-coated aluminum for strength and rust resistance. The electric motors are all commercial grade and maintenance free. The Shotmaker also incorporates several distinctive features to enhance usability, including a single electronic panel to control all functions. The Shotmaker control panel is conveniently located at the back of the machine about waist level to allow operation in a natural standing position. You can easily dial-in the tennis shots you want while observing the entire court in front of you. A see-through, high-impact plastic cover provides extra protection for the control panel. The Shotmaker also includes four (4) oversized caster wheels for easy rolling on and off the court and a protective all-weather cover to protect your investment. The Shotmaker® Standard with 2-Function Remote has a control panel that is organized in two simplified sections. The left side of the control panel controls the type of shot you want. Individual dials set Speed, Spin, and the Interval between shots, while simple switches control Power (On/Off), Elevation (Higher/Lower) and Remote (On/Off). The right side of the control panel can be programmed to shoot balls to any or all of the three positions (A, B, C) shown on the tennis court diagram above the switches. The Optional 2-button Remote lets you start and stop ball delivery, and control the side-to-side position of the ball throws.
