Dynaflex SM-01 Speedometer for Dynaflex Power Balls
Designed to work with the DynaFlex Pro Plus and Powerball gyros, this digital speed meter upgrades the performance of both machines. The speed meter offers three important functions: it measures the user's current speed, remembers the user's highest rpm, and calculates the maximum revolutions of the gyro. As a result, it's possible to keep precise track of your rehabilitation progress, or you can challenge yourself or your friends to see who can achieve the highest speeds. Plus, it's a breeze to install the speed meter--just remove the cap of the gyro and snap the meter into place.
