What Thor Guard does
Thor Guard Inc. is a privately held Sunrise, Florida-based manufacturer of lightning prediction and warning systems, founded in 1973 by inventor Bob Humphreys and led since 1987 by President Bob Dugan. The company differentiates on a PREDICTION-versus-detection thesis: its TG360 and TG360 Hybrid sensors sample atmospheric electrostatic fields at over 170,000 times per second, applying proprietary algorithms refined over 50+ years of accumulated atmospheric and lightning-strike data to deliver 8-20 minutes (and sometimes up to 45 minutes) of advance warning before the first strike within a 2-mile radius, claiming 97% accuracy when alarms activate. Supporting products include the Voice of Thor (VOT) horn/strobe warning system, portable Nomad units, marine-rated Neptune units, ThorServer central management software, and ThorAlert mobile applications.
The company has deployed more than 7,000 systems worldwide and reports a 99.8% customer retention rate. Revenue is generated through one-time hardware sales (with quoted project values ranging from roughly $10,000 for a single sensor installation to $98,000-$160,000 for countywide or citywide multi-zone deployments), recurring software subscriptions, annual maintenance contracts, and professional services including on-site meteorologist support at major sporting events. The go-to-market combines direct enterprise field sales to municipalities, school districts, airports, and sports venues with channel partnerships in the golf vertical (TPC, Marriott, PGA Tour, USGA, LIV Golf, European Tour) and certified installer networks for deployment. Customer concentration spans four primary verticals: golf courses, parks and recreation, K-12 and higher education, and aviation, with anchor reference accounts including all TPC courses, all Marriott courses, USGA championships (since 1994), American Airlines, and Delta. No external funding rounds, M&A, or institutional investors are disclosed; the company is founder/operator-owned and continues to reinvest via product refreshes (TG360 and TG360 Hybrid in 2024) and ongoing municipal and beach deployments.

Thor Guard product offering
Product offeringCore offering
Thor Guard manufactures and supplies lightning prediction systems that measure atmospheric electrostatic field energy buildup to predict lightning strikes 8-20 minutes before they occur. The company offers hardware systems (sensors, horns, strobes, control units) supported by software platforms (ThorServer, ThorAlert mobile app, ThorMobile/ThorTV) and on-site meteorologist services for major events.
Product overview
Thor Guard offers a comprehensive portfolio of lightning prediction and warning products. The core offering centers on the TG360 and TG360 Hybrid systems, which provide real-time lightning prediction by analyzing atmospheric electrostatic fields at over 170,000 samples per second. Supporting products include the Nomad and Neptune for portable and marine applications, Voice of Thor (VOT) for audible warning systems, ThorServer for centralized data management, and ThorMobile/ThorTV plus ThorAlert for mobile and remote monitoring. Together, these products form an integrated safety ecosystem that monitors atmospheric conditions, predicts lightning strikes 8-20 minutes in advance, and delivers multi-channel alerts (horns, strobes, mobile apps, TV displays) to protect people at outdoor venues, golf courses, schools, beaches, and municipal facilities.

Thor Guard competitors and assessment
Company assessmentDirect peers
- Earth Networks: Earth Networks operates the Sferic Maps lightning detection network and provides enterprise weather data feeds to sports venues, schools, and outdoor facilities. Direct peer because its Sferic product competes head-to-head with Thor Guard for outdoor venue and school lightning alerting contracts.
- Campbell Scientific: Campbell Scientific manufactures rugged weather and environmental monitoring instruments and data loggers used at research stations, agriculture, and industrial sites. Direct peer because it serves the same atmospheric monitoring customer base with sensor + data acquisition systems, though with a research/industrial tilt rather than public safety.
- Vaisala: Vaisala is the global leader in environmental and industrial measurement, including the GLD360 global lightning detection network. Direct peer because it manufactures commercial lightning detection and weather observation systems sold to aviation, defense, and meteorological customers — the same buyer base Thor Guard addresses.
- Biral: Biral is a UK-based manufacturer of lightning detection sensors and meteorological instruments serving aviation, defense, and research markets. Direct peer because its lightning warning systems compete with Thor Guard in aviation and military customer segments where safety-certified lightning detection is required.
Broad incumbents
- AccuWeather Enterprise Solutions: AccuWeather Enterprise Solutions provides site-specific weather forecasting and lightning alert services to enterprise customers across sports, transportation, and government. Broad incumbent because it offers overlapping safety alerting via subscription rather than dedicated hardware, competing for the same enterprise budget pools.
- Honeywell (Aerospace weather systems): Honeywell provides weather radar and lightning detection systems to commercial aviation operators through its Aerospace division. Broad incumbent because it competes for the airport and aviation customer segment that Thor Guard serves with American Airlines and Delta, but as part of a much broader aerospace portfolio.
Emerging players
- Davis Instruments: Davis Instruments manufactures consumer and prosumer-grade weather stations including Vantage Pro2 systems that include basic lightning detection. Emerging player because its products address the lower-cost end of the weather/lightning monitoring market with partial overlap to Thor Guard's smaller commercial and park installations.
- WeatherFlow-Tempest: WeatherFlow-Tempest operates professional-grade weather station networks and consumer lightning-detecting smart weather stations. Emerging player because its networked station model represents a different architectural approach to outdoor lightning alerting that competes with Thor Guard for community and venue deployments.
- All Weather Inc: All Weather Inc manufactures aviation weather observation systems including lightning detection for FAA-certified airports. Emerging player because it serves a narrower aviation-and-research niche with partial overlap to Thor Guard's airport and aviation customer base.
