The Impact-Alert Sport-Tuned™ Sensor alerts the users to significant impacts received while participating in various sports. The sensors are designed to measure significant impacts while wearing a helmet. Thus, alerting you to replace a damaged helmet and/or monitor for concussion type symptoms.
While wearing a helmet, if one sensor activates (turns red) it indicates a significant impact. If both sensors activate during use, they indicate a very significant impact and the participant should be monitored for symptoms of concussion and the helmet should be replaced.
Please note, some helmets with rigid foam liners (ex. cycling, alpine, etc.) can be damaged when dropped onto a hard surface regardless if the helmet is in use or not.
