ABSTRACT:
A hand-held electronic apparatus for the detection and ranging of lightning strikes wherein radio frequency signals from lightning activity are filtered to allow selected low frequency emissions to be compared with standard voltages in order to activate light emitting diodes which correspond to distances to lightning activity: 0-10 miles, 10-20 miles, etc. The device only the electrostatic field component of the radio signals from lightning activity. The electrostatic component typically dominates over the electromagnetic component at comparatively short distances of 40 miles or less.
