The Pro Plus is the intermediate level gyro and is a great balance between the Sports Pro Lighted Powerball gyros. The Powerball Sports Pro gyro uses resistance force to generate up to 35 pounds of torque and 13,500 RPM and is the ideal product for anyone looking to improve dexterity, strength, coordination and accelerate healing time. If you don't need the high-end Lighted Powerball but want more than the entry-level Sports Pro, then the Powerball Sports Pro Plus is for you! The Powerball Pro Plus model has a balanced rotor and is compatible with the digital speed meter and the power docking station. The Powerball Sports Pro Gyro is packaged with the gyro training CD and starter cord. The Speed Meter (370954) is compatible with the Powerball series and the Powerball Pro Plus series.
