The Exeter school district has taken that one step further with the purchase of 145 Riddell SpeedFlex helmets, equipped with the InSite monitoring system. The district ponied up more than $55,000 last spring to equip all of its high school and junior high players with the latest technology. It seems to be money well spent.The monitor receives signals from each helmet, which are equipped with Riddell's InSite Impact Response System. When a player sustains a hit that exceeds a preset impact threshold, the monitor sends out an alert. Athletic trainer, Audrey Dickman has experienced the first hand benefits of implementing this system into the Exeter football program.
