The Boltek LD-350 Lightning Detector puts a live lightning map on your laptop or desktop computer. Within milliseconds of a lightning strike the detector beeps and your computer displays the strike location. The LD-350's direction-finding antenna measures lightning strike direction while the LD-350's receiver 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.

The LD-350 can warn of both close and severe thunderstorms. If a storm is detected closer than a preset distance or the strike rate exceeds a preset limit, the LD-350 sounds its internal alarm and activates the computers alarm tone or WAV file notification. Both the Close Storm and Severe Storm alarm statuses are indicated on the LD-350's front panel.

Strike rates, both Close Strikes / Minute and Total Strikes / Minute are shown for the previous hour on the Strike Rate Trend Graph letting you easily see if storms are increasing in severity or dying out.

Multiple display ranges allow you to zoom into the region of interest. Zoom out to the maximum range of 750 miles (1200 kms) or zoom in as close as 16 miles to view only the nearby storms

LD-350 lightning data is live! Your computer beeps and displays the strike within milliseconds of the strike happening! With the LD-350 Lightning Detector you are actually detecting the lightning strikes themselves. There are no on-line or recurring charges of any kind.

LD-350 Lightning Detector has two built-in alarms: a Close Storm Alarm and a Severe Storm Alarm. The Close Storm Alarm will activate if a thunderstorm is detected closer than a preset distance. The Severe Storm Alarm activates if the number of lightning strikes per minute exceeds a preset limit.

The LD-350 will sound an alarm tone when either alarm activates. Front panel pushbuttons allow both the Strike tone and Alarm tones to be disabled.

The computer can also be configured to sound an alarm tone and/or pop up a notification window when an alarm activates. Alarm status is indicated by the color of the Close Storm distance circle and Severe Storm status indicator in the top left corner of the map window.
