Product overview
The Flash Weather Shield is the industry's first fully customizable predictive weather notification system. Where legacy detection units only sound off after lightning is already nearby, Shield is wired to Flash's 1-hour predictive lightning model, so the horn or strobe fires before the first strike lands, not after.
Three configurations fit different environments. The full Flash Shield is the gold standard for large outdoor operations, with four horns standard (up to eight) and coverage built for entire golf courses and complexes. The Mini is a compact two-horn unit sized for clusters of soccer or baseball fields, often deployed near busy roads where ambient noise would drown out a smaller siren. The Micro is built for spaces like pool decks, outdoor dining patios, and other settings where a full siren would be disruptive, with a multi-colored strobe that shows real-time status: green for all clear, amber for warning, and red for alert. The siren can even be removed entirely for quiet zones.
All units are solar-powered with cellular connectivity, so each one operates as a standalone command center for the property. Shield replaces the archaic "30 minute rule" with dynamic, data-backed alerts grounded in lightning prediction that is up to 99.6% accurate. Safety happens before the storm, not in reaction to it.
