Thank you for your interest in the ThunderBolt Storm Detector. The ThunderBolt detects and tracks storms from 75-miles, providing the user with the Estimated Time of Arrival for approaching storms. Once the storm becomes Local (8 miles), the ThunderBolt provides the user with the Time to Clear (the time necessary for the storm to clear the area inorder to resume outdoor activities). The rugged ThunderBolt has been in use by the most demanding customers worldwide, including all branches of the armed forces, national laboratories, oil refineries and rigs, mining operations, construction companies, schools and universities, youth sports, boaters, campers, and many more.
