The Armasight Helios line is the latest and most technologically advanced family of thermal imaging bi-oculars on the market today. Bi-ocular design is better for sustained viewing periods and improved depth perception. Thermal imaging technology allows you to detect targets by cutting through snow, dust, smoke, fog, haze, and other atmospheric obscurants. Unlike the use of laser targeting or nearinfrared illumination to augment night vision equipment, Helios thermal imagers are extremely difficult to detect with other devices, as they emit no visible light or RF energy.
