Riddell InSite: Key Distinguishing Features


What makes Riddell InSite different from other impact response systems?

  • The alerts are based on head impact, not helmet impact
    • According to a recent research paper analyzing football helmets equipped with a version of the Head Impact Telemetry System (HITS) used in the InSite Impact Response System,1 HITS accurately measures head acceleration, which is less than 10 percent of helmet acceleration in football impacts. 
  • Grounded in research: It uses alert methodology based on over 2 million recorded on-field impacts using the Riddell SRS system.
  • Uses HITsp for Alert thresholds, using a proprietary algorithm which takes into account linear and rotational acceleration, duration and location of impact.
    Riddell InSite Impact Response System
  • Identifies over-exposure of single as well as multiple impacts (seven day accumulation of significant impacts)
  • Measures head impact on five key, distinct locations in helmet
  • Has ability to program thresholds by player position and level of play:
    • Player Position
      • Quarterback
      • Running Back
      • Offensive Line
      • Defensive Back
      • Linebacker
      • Defensive Line
      • Special Teams
      • Wide Receiver
    • Level of Play
      • Youth
      • High School
      • College
      • Professional
  • Designed to last up to four years with proper reconditioning (to replace battery)
