The TENNIS TOWER IO is a mid-priced professional ball machine with top-of-the-line features. I.O. stands for Internal Oscillation, which means that only the ball-throwing mechanism inside the machine moves to change the side-to-side position of the ball throws, instead of pivoting the entire machine. Internal Oscillation disguises where the ball will be thrown, and is also much quicker throwing balls from spot to spot.

Optional AC/DC capability can eliminate extension cords.

TOWER IO Player Model

  • 2-line oscillator feature – Shoots balls to two preset positions. This allows a player to practice alternating forehand and backhand shots, and helps an instructor work with two lines of students in a group lesson. There are two 2-line settings: Narrow & Wide.


Additional Remote Options for Player Model

Multi-Function Remotes – Wireless control of all functions just like you were using the actual control panel. The layout of the buttons on the remotes is almost identical to the layout of the buttons on the control panel, so there is nothing new to learn.  There are two Multi-Function Remote choices.

  • FM Multi-Function Remote – Small handheld unit. ($300) 
  • Phone Multi-Function Remote – Requires free App download.  Available for both Apple and Android phones.  Automatically connects instantly via bluetooth with no need for a wireless broadband connection. If this option is purchased a bluetooth receiver is installed in the machine. ($300)
