Thunderstorm Detector for your home

Did you hear about the kid who got his head seared by lightning while listening to his iPod? Perhaps if he had paid attention to the Thunderstorm Detector, this untoward incident would not have happened. This device is capable of detecting cloud-to-ground lightning strikes up to 75 miles away, giving users an accurate, reliable warning long before thunder gets audible and storms visible. Since lighting can herald a storm up to 10 miles in advance, having the Thunderstorm Detector could help save your life. It 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. A single 9V battery offers up to 90 hours of operation. The Thunderstorm Detector retails for $429.95 each. Every home should have one unless you live in either Poles or somewhere in the middle of a desert.
