The Sports Tutor Tennis Tower IO is a mid-priced professional ball machine with top-of-the-line features. The I.O. stands for Internal Oscillation, meaning that only the ball-throwing mechanism inside the machine moves to change the side-to-side position of the ball throws, rather than pivoting the entire machine. This feature helps disguise where the ball will be thrown and allows for much quicker ball delivery from spot to spot, making training more unpredictable and game-like.

With a ball capacity of 225 balls, it allows for extended training sessions without frequent refills. The machine offers adjustable speeds ranging from 10 to 85 MPH, making it suitable for players of all skill levels. The ball feed rate can be customized between 1.5 to 10 seconds, providing flexibility in pacing. Spin control settings allow users to practice against both topspin and underspin shots. The electronically adjustable elevation system enables players to practice different shot types, from groundstrokes to lobs.

The Tennis Tower IO is available in multiple configurations, including the Tower Classic, Tower, and Tower Player, each offering different features tailored to various training needs. Sports Tutor provides a three-year warranty covering both parts and labor, ensuring long-term reliability. Overall, the Tennis Tower IO is a powerful training tool for tennis players seeking a professional-grade ball machine with customisable features to enhance their game.

Two upgrade models are also available:

The Tennis Tower IO Player Model is designed to simulate a real opponent with its Patented Player Mode, which automatically adjusts speed, spin, and shot depth to mimic Beginner, Intermediate, and Advanced-level players. It includes a two-line oscillator feature, allowing players to alternate between forehand and backhand shots or enabling coaches to train two players simultaneously. This model is ideal for those seeking more dynamic and varied practice sessions.

The Tennis Tower IO Deluxe Model builds upon the Player Model’s capabilities with enhanced programmability. It features a Quick Set-up mode, where users can select Beginner, Intermediate, or Advanced difficulty for automatic ball delivery. The Shot Program Memory allows users to create and store up to eight custom shot sequences, with each shot directed to different court positions or set to random placement. This model is perfect for players who want a fully customizable and strategic training experience. Both models offer optional Multi-Function Remotes, including an FM handheld remote and a smartphone-controlled Bluetooth remote.
