    The LD-250 puts a live-action lightning display on your computer screen, showing storm activity up to 300 miles in all directions from your location so you can track position, speed, and direction. With optional GPS or Fluxgate compass, you can use the LD-250 to chase or avoid storms in your car, truck, or boat.

    A self-contained device, the LD-250 is constantly seeking lightning strikes even if the computer is turned off. An audible alarm and blinking light will alert you to turn the computer on and receive full data whenever strikes are detected. Front panel lights and audible alarms also indicate when storms are close, severe, or both, according to standards determined by the user. Your computer can be set to sound an alarm or show a pop-up window to indicate close or severe storms.

    The LD-250 is available as either a basic kit, with all the parts you need to start monitoring lightning strikes and displaying them on your computer, or as an advanced kit. The advanced kit includes pole mount hardware for the Lightning Antenna, a full version of the NexStorm Lightning Software and a CVM Custom Vector Map for your location. When ordering the advanced LD-250K please enter the longitude and latitude to which your CVM should be centred to. Once your order has been received your CVM will be generated and emailed to you electronically.
