The purpose of the vision ball markings is to encourage participants to watch the ball all the way into their hands. A coach or parent then asks what colour they last saw or which shape they saw when they caught the ball. Used together with the Crazy Catch it provides the facilities for young ones to learn and obtain the basics motor skills that will assist them with their sporting life in years to come. Vision Ball 3 is a solid fill ball for the gifted and talented athlete. It responds more erratically than the Vision ball 2.
