  
Never get caught by an unexpected thunderstorm again! The hand-held ThunderBolt Pro Storm Detector keeps you out of danger - detecting storm activity and giving you ample time to seek shelter & safety. The ThunderBolt Pro can detect storm activity within 75 miles of your location. It identifies multiple storm cells, squall lines & super-cells using state-of-the-art storm and lightning detection and it's patented warning system technology. ThunderBolt Pro provides an estimated time of arrival at your location and calculates the "Time To Clear" once a storm is near enough to be a threat. It communicates through text messages (over 50 different messages), flashing lights and user-selectable audible tones. The ThunderBolt Pro studies the anatomy of a storm, processes the storm data and warns the user of storm distance, approach speed, intensity, and estimated time of arrival. The portable ThunderBolt Pro Storm Detector analyzes thunderstorm & lightning activity independently of any broadcast weather source, providing real-time weather warnings. The ThunderBolt Pro is completely self-contained. It works by detecting electromagnetic activity from lightning flashes; then the microprocessor analyzes the waveform & voltage levels of the storm. The microprocessor transmits that data to the LCD screen, displaying vital information in the form of text messages. The ThunderBolt Pro continuously "filters out" the background electromagnetic interference at your location to minimize false triggering of storm warnings. Who needs the ThunderBolt Pro? Sports teams, fishermen, boaters, golfers, cyclists, campers, hikers, anyone who spends time outdoors! The ThunderBolt Pro comes complete with a custom-fitted, hard-sided carrying case, 120-Volt AC adaptor and owner's manual. The ThunderBolt Pro carries a lifetime warranty.
