The ThunderBolt Pro Storm Detector discerns storm activity from as far as 75 miles away and provides ample time to seek shelter. It analyzes thunderstorm and lightning activity independently from any broadcast weather source, eliminating time delays in reporting dangerous weather warnings with real time weather data. Comes complete with a custom-fitted, hard-sided carrying case, 120-Volt AC adaptor, desk stand and owner's manual.
Once ThunderBolt detects a storm, it calculates the actual distance in miles and displays warning information on an easy-to-read LCD display. The ThunderBolt then continuously provides weather safety information by monitoring the storm and providing 15-second updates on the distance, approach speed, intensity, and Estimated Time of Arrival (ETA) to the user’s exact location. It also provides the Estimated Time to Clear (ETC), which informs the user when it is safe to resume outdoor activity after the storm has cleared an eight-mile range. Flashing lights and an audible alarm provide warnings in a variety of operating environments.
