Thermal Night Vision uses heat to see instead of amplifying light like digital or image tube night vision.
Unlike night vision, thermal night vision can see no matter the light level. Even in total darkness and poor weather conditions, thermal night Vision technology allows users to detect and see at great distances.
This ability to see when image intensification tube night vision and digital night vision can not gives thermal night vision a distinct advantage. This advantage is especially apparent for nighttime predator hunting where light levels are much lower than in urban environments.
