TORNADOLERT - recommended for homes, trailers, apts, schools, nursing homes, cars, RVs, trucks and tornado shelters. Faster and more reliable tornado warnings. VIDEO of operation in homes and cars.
Tornado-Warn detects infra-sound strongly radiated by every tornado.
National Oceanic & Atmospheric Administration has demonstrated ultra-reliable tornado detection using this method.
Because infra-sound travels without loss through solid walls, Tornado-Warn (Home) may be located anywhere in homes, apartments and tornado shelters.
Tornado-Warn (Car) is the only sensor detecting tornados in moving cars and trucks.
Other tornado sensors detect lightning-storms, not tornados. However, only 10% of lightning-storms actually produce tornados.
