Since 1976 THOR GUARD systems have reliably and accurately provided advance warning of the potential for lightning for thousands of satisfied customers. In a developing storm, this unique protection technology evaluates the dynamics of the electrical energy within the atmosphere and will automatically provide timely warning alerts. Waiting for a strike to occur may be too late.

A significant difference between THOR GUARD and other lightning warning systems is that this is based on "time" and the others are based on "distance". The THOR GUARD system is designed to give a "Red Alert" warning eight (8) to twenty (20) minutes in advance of a potential strike in your area so you can find shelter. Other systems tell you how far away lightning just struck so you can decide when to find shelter.
