Relyon's Thor Guard Model L75 is our first upgradeable base prediction and warning system control center. Customers can now have an entry level system, automatic or manual, capable of providing an audible and visual warning for a single site.

Thor Guardian

The ThorGuardian is the first, completely integrated, advance warning system for lightning. The entire package, including the lightning prediction system, integrated horn cluster, and strobe light, can all be easily installed outdoors. Standard AC powered and solar powered options are available.

Voice of Thor

The Voice of Thor horn system allows a base horn cluster, and/or optional remote horn cluster, to be controlled by the lightning prediction system through RF communication. Base and remote horn clusters have battery back-up with standard AC powered and solar powered options available.

Since 1993

Our systems are designed to constantly monitor the ongoing increase or decrease in intensity of the electromagnetic field to generate a prediction of lightning occurring in your immediate area (typically within a 2-2.5 mile radius). During any given outdoor activity, whether a ball game at a neighborhood park, a golf tournament, or outdoor construction, Thor Guard systems take the guesswork out of lightning-related decisions — not only when it is time to stop and take shelter, but just as important, when it's time to resume an outdoor activity.



Simply ask yourself, how many times have I been outdoors when a sudden flash and loud rumble unexpectedly interrupt my activities? Even during clear weather or hazy skies, electrostatic forces are hard at work developing a field between a building thunderhead and the earth. It is this field that determines when and where a lightning strike is likely to occur.
