StrikeAlert is a small (about the size of a pager) and affordable lightning detector that provides an early warning of approaching lightning strikes from as far away as 40 miles and lets you know if the storm is coming your way. Its designed for personal and portable use.
An audible alarm sounds when there’s a strike and a corresponding LED light illuminates accordingly at lightning distances of 20-40 miles, 12-24 miles, 6-12 miles and within 6 miles.
I tested this product during the 2009 season and found it to work very well. It came in handy while watching distant storms.
It’s small, only the size of a pager and can be used by anyone from storm chaser, TV crews, sports officials, anyone who spends time outdoors.
