The EWS-PRO 2 offers you the ability to detect the presence of Iightning/thunderstorm activity occurring within 40 miles of your location. EWS-PRO 2 detects the characteristic electromagnetic emissions from individual lightning strokes and uses patented technology to determine the distance to the detected stroke. The distances are indicated in four ranges: 0-3 miles; 3-8 miles; 8-20 miles; and 20-40 miles. This allows you to track the approach of dangerous storm activity.

   The EWS-PRO 2 may also identify certain types of especially strong storms. These storms can produce dangerous winds, heavy rains or tornadoes. When EWS-PRO 2 detects lightning patterns indicating the presence of these storms, it activates the Severe Thunderstorm Alarm and emits a distinctive 15-second continuous audible tone different from the detection of normal lightning activity.
