Reebok Checklight

Head injuries in sports have been getting a lot of play lately, and for good reason, they're extremely dangerous and hard to diagnose. The Reebok Checklight ($150) helps players monitor the number of, and severity of head impacts throughout the game, so coaches, officials, and medical staff can know just how to react. The sensor fits easily into an included skullcap, making it comfortable to wear with, or without a helmet. A status light gives valuable, realtime feedback, letting you know exactly how bad the hit was, and how many you've taken.
