Thunderstorm Warning from Up to 40 Miles Away
Knowing the average lightning strike is six miles long and that thunder can generally be heard over a distance of 3–4 miles, it isn't very difficult to understand why many lightning deaths and injuries occur with clear skies overhead. The compact SkyScan™ Lightning Detector uses a fully digital microprocessor enclosed in a weather-resistant ABS case to scan for the electronic traces of a lightning storm. By using separate audible and visual alerts, the unit is able to give you the approximate distance of an existing storm in miles (0–3, 3–8, 8–20, 20–40). An available AC Adapter, Carrying Case and Wall Mount are sold separately.
