Announced at FDIC in April, 2009, EchoSeeker™ represents the state-of-the-art in sensor fusion for Firefighter Locating systems. EchoSeeker seamlessly integrates an ultrasonic tracking device into the ISI 3500 thermal imaging camera (TIC). EchoSeeker is fully-functional and capable locating any Pathfinder™ Beacon (Firefighter/RED, Auxiliary/YELLOW, or Exit/GREEN). Its simple and intuitive interface allows the firefighter to focus on navigating to the victim while simultaneously being aware of the surrounding conditions.

EchoSeeker attaches directly to pre-existing ISI thermal imaging cameras, between the battery pack and the unit itself. When thermal imaging and ultrasonic technology are combined, the result is a unit that can dramatically decrease rescue time. With two-button operation, light weight binocular style design, and slide-on external battery, ISI EchoSeeker is user-friendly and simple to operate. That precious time could be the difference between performing rescue and making a recovery. The ISI 2500 and ISI 3500 thermal imaging cameras provide the highest standard of imaging performance available.
