Using hand rotation, spin the internal gyro and challenge yourself and others to achieve the highest revolution per minute.

Pull the cord to spin the gyroscope inside the ball. Rotating the ball in your hand increases the rotation of the gyroscope. The digital counter measures the speed of the gyroscope and displays the number of revolutions per minute (RPM).

Good training for golfers, racket sport enthusiasts or simply good competitive and addictive fun.
