The ClearBall is clear in appearance and therefore harder to see, it forces the player to have to rely on FEEL more than sight. This is a great training aid to get stickhandlers away from watching the ball/puck while stickhandling.  By doing this it allows the player to skate with the puck while keeping his/her head up and therefore being able to "see the ice", a critical skill for any hockey player who wants to be a playmaker.
