Feel the correct plane and release with the Sklz Gyro Swing Golf Training Aid. You can “feel” a proper swing instead of worrying about positions and mechanics. The device forces your swing to stay on plane and grooves a timed release. The concept of this device is a gyroscope which can maintain a perfect arc around the centre point in space.
