Firefighters face many dangers, including burns, smoke inhalation and structure collapses. Because they're required to wear all that heavy gear while performing strenuous activities, however, they also risk heat stroke. That’s why firefighter Michael Robinson invented the HeatSeeker – a device that attaches to a fire truck’s existing hose port, creating a cooling mist.

Robinson came up with the idea just last October, when he saw how tired some of his fellow firefighters looked after responding to their third fire within one shift. He proceeded to develop a gizmo that he called the Sixshooter – a chrome-plated brass cap, equipped with six misting nozzles made by Ecologic Technologies.

The idea was that the device could be attached to one of the unused hose ports on a fire truck, providing a cooling mist that firefighters could step into to keep from overheating. Unlike already-available fans and misters, it would require no power source, and take up no more room than a regular hose port cap.

An improved version of that device is now commercially available as the HeatSeeker. It reportedly sets up in seconds, uses “minimal water,” and can cool an area by up to 30 degrees Fahrenheit.

Different sizes and configurations of HeatSeekers are available, with prices ranging from US$59.99 to $119.99 – powder coat finish and engraving are extra. Non-firefighters can also check out the HotShot model, which is designed to fit on the end of a garden hose for home use.
