Spectrum ThunderBolt Utility BL
Storm & Lightning Detector with BackLit Display

Spectrum ThunderBolt Utility BL YellowSpectrum ThunderBolt Utility BL Black

The Spectrum ThunderBolt® Utility BL Storm & Lightning Detector with BackLit Display is the highest professional-grade portable lightning detector offered by Spectrum and comes complete with a full range of accessories that allows for maximum flexibility in use and installation. This personal, hand-held weather monitor utilizes self-contained proprietary software and electronic technology to detect and track the motion of thunderstorms. It analyzes lightning activity within storm cells and supercells, and is capable of identifying the presence of squall lines, which can occur in conjunction with thunderstorm activity. Storms are detected and analyzed within 75 miles of the user's location. ThunderBolt's advanced proprietary technology converts data from the intensity of electro-magnetic field emissions of lightning activity within a storm cell into digital signals. The signals are then fed into a microprocessor for analysis. The unit tracks and alerts the user through text messages on its BackLit Liquid Crystal Display (LCD), red and green Light Emitting Diode (LED), audible tone warnings, and ThunderBolt Emblem warning light.

The ThunderBolt® Utility BL package includes a custom fitted hard-sided field carrying case, soft carry pouch, custom wall mount, 120-volt AC adapter, Duracell PROCELL battery, and a custom desk stand with an external connector jack for attachment of the Control Module for the Remote Warning System of optional accessories (jack not available on the standard ThunderBolt PRO BL).
