According to the National Weather Service, your odds of being struck by lightning in a given year are 1/400,000. If you don't like those odds, you'll want the StrikeAlert Personal Lightning Detector. It may look like pager, but it will detect lightning from 40 miles away and let you know if it's headed in your direction. An alarm alerts you to a strike and an LED flashes at incremental distances so you can track the lightning's approach. It's available for $80.
