About the USPLN

The United States Precision Lightning Network™ (USPLN™) was built in 2004 responding to customer demand for an alternate lightning detection solution. From the start, the goals of the network partners were to provide the highest level of accuracy and efficiency for operational and consumer needs, while ensuring this critical information could be obtained at a lower price point.

The end result has exceeded these goals and has revolutionized the lightning market place. Today's customers have the benefits of choosing from multiple providers and determining the best solution for their requirements. We encourage lightning users to read about our advantages and contact us for pricing and more information.

By virtue of the underlying technology, the USPLN provides the highest quality and accuracy real-time and archive lightning stroke detection data. This data serves as the basis for a variety of products and services developed by WSI and our Value-Added Resellers. With approximately 100 sensors covering the continental United States and expanded coverage availability for North America, the USPLN data is timely, accurate, and comprehensive.
