The General LD9 Portable Strike Alert
Used by golfers, campers, law enforcement, sports officials and other persons who work or recreate outdoors.
This unit is a personal and portable unit that can be worn clipped to your belt. It can sense lightning up to 40 miles away and can determine if a storm is approaching or departing. It has a loud audible alarm and multiple LED lights to approximate distance. Also, the number of alarm beeps will indicate the proximity of lightning.
The LD9 is a small, impact-resistant pager-like design that displays lightning strike distance, storm direction and battery life. It measures 2.85" x 1.85" x 0.75" and weighs only 2.75 oz. (w/o batteries). The LED’s indicate ranges from 0- 6 miles, 6-12 miles, 12-24 miles and 20-40 miles.

About Lightning Detectors
A lightning detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors: a ground-based system, a battery operated mobile system and a space-based system.
One type of lightning detector which is rapidly increasing in popularity is the battery-operated personal lightning detector. Similar in size to a pager, personal lightning detectors are popular among golfers, campers, law enforcement, sports officials and other persons who work or recreate outdoors. Personal lightning detectors function by detecting the electromagnetic pulse emitted by a lightning strike. By measuring the strength of the detected EMP, the device can then estimate how far away the detected strike was. When exposed to multiple detected strikes, some personal lightning detectors can even calculate and extrapolate the direction of the storm's movement relative to its position (approaching, departing or stationary).
