Strike Alert HD Lightning Detector
This is the first personal lightning detector with a graphical display that shows the lightning strike distance! Measures up to 40 miles away. Also displays 1-hour trend and intensity of the storm. Tracks lightning in all directions! An audible and/or vibrate warning gives alerts before and while lightning is within striking distance. LED indicators light accordingly at lightning distances of 24-40 miles, 12-24 miles, 6-12 miles, and within 6 miles. Informs when it has been 30 minutes since the last strike, which is the NFHS minimum standard for suspended play. Uses low power consumption, up to 80 hours of operation with two AA batteries (included).
