Thermal sights detect heat signatures instead of relying on visible light, so they can identify targets in complete darkness and in low light. The category covers thermal weapon sights, including thermal and red dot combination sights. Military users, law enforcement officers, and hunters all rely on thermal sights for night work.

Options include thermal and red dot combination sights and more from top brands like Holosun. Models differ in sensor resolution, zoom, video recording, and battery or charging type.

Choose the sight based on the job. Thermal sights are used to scan for heat at night, such as finding a person or animal in a field or along a tree line. A thermal and red dot combination sight can be used as a red dot in daylight and switched to thermal when it gets dark, so one optic covers both. Thermal imaging does not see through glass, so it is used in open air rather than through a window or windshield. Features vary by model, including sensor resolution, selectable zoom, video recording, and USB charging, so match them to how the sight will be used. Hunters should check local regulations on thermal use before heading out.

Compare thermal sights with rifle red dots and holographic sights for daytime use. See more optics for the rest of the setup.
