The Boltek LD-250 Lightning Detector puts a live lightning map on your laptop or desktop computer for boat. Within milliseconds of a lightning strike the detector beeps and your computer displays the strike location. The LD-250's direction-finding marine antenna measures lightning strike direction while the LD-250's receiver for boat estimates distance from received signal strength. Advanced signal processing in software improves distance accuracy, reducing the effects of strike-to-strike variations in strike energy.
