The ThunderBolt™ TB-U1 Utility model is designed with these three critical needs of the commercial application in mind:

SAFETY: Because the ThunderBolt is totally self-contained and detects the storm directly using the electromagnetic signals of the lightning, it provides instant storm warning. The portability of ThunderBolt allows you to take it wherever and whenever to help protect the lives and increase productivity of your workers. Whether on an extended commercial or industrial site, or on an isolated job site, the ThunderBolt effectively provides critical storm safety information.

Even for non-technical users, the ThunderBolt is easy to use and understand. Its proprietary software turns the complexities of storm tracking into simple text messages, detecting storms out to distances of 75 miles, determining distance and approach speed (ETA), and immediately warning a user when a storm becomes a LOCAL threat.

PRODUCTIVITY: Even more important when protecting lives and enhancing productivity is the knowledge of when it’s safe to resume outdoor activities. ThunderBolt provides this information as part of the standard storm tracking function by displaying the TIME TO CLEAR, and updating this information as the unit tracks the trailing edge of the storm. As a result, ThunderBolt safely maximizes storm day productivity.

LIABILITY: It’s what you can’t see and can’t hear that represents the greatest danger to your business. When you consider that 60% of all lightning injuries and fatalities occur when the storm activity seems to have passed, and 30% before you’re aware a storm is coming, you can understand that this is perhaps the most important information required to protect lives and limit liability. Information only ThunderBolt provides.

It’s all about SAFETY, PRODUCTIVITY and LIABILITY. ThunderBolt protects your employees, your customers, and your business from thunderstorm danger.
