Memory Spot Down Indicator
Never wear two down indicators again! Designed with referees and umpires in mind this modification to a traditional down indicator includes a horizontal position indicator. A durable viewing window slides along to one of five spot indicators to accurately track the lateral position of the ball. Stop the slide anywhere in between the markings to know exactly where the ball should be spotted. Designed to move easily ---but not move on it's own -- the first time you use it will undoubtedly be the last time you ever wear two down indicators!
