The 75-Mile Range Thunderstorm Detector.
WAS 429.95 NOW 249.95
This is the device that detects cloud-to-ground lightning strikes up to 75 miles away, providing an accurate, reliable warning before thunder is audible or storms are visible, allowing you to seek shelter long before the approach of storm cells. Lightning can precede storms up to ten miles away, and, once a storm has passed, can still strike up to the same distance, so the detector will alert you using a flashing red LED, an audible alarm, and up to 50 distinct text messages on its easy-to-read LCD until the danger of lightning has completely passed. The detector uses a highly-sensitive ferrite antenna that detects the low-frequency radio signals, or sferics, emitted by lightning
as they travel through the earths ionosphere. Its built-in microprocessor and software analyzes the waveform and voltage the antenna detects to tell you how far away a lightning strike was, which indicates the presence of approaching storm cells and squall lines, and provides you with storm approach speed, estimated time of arrival, distance, and more. The detector also performs continuous analysis of background electromagnetic signals at its location in order to differentiate between storm/non-storm sources. One 9-volt battery (required) provides up to 90 hours of operation; includes AC adapter and hard carrying case. 6 1/2" L x 3 1/2" W x 1" D. (10 3/4 oz.)
