A handheld laser rangefinder is a precision electro-optical device that measures the distance to a target by emitting a laser pulse and calculating the time it takes for the reflected signal to return. Known for its high accuracy, fast response, and ease of operation, this technology is widely used in both civilian and professional fields where reliable distance measurement is critical.
Modern handheld laser rangefinders are increasingly integrated with night vision, positioning, and navigation systems, making them essential tools for night-time operations, long-range observation, and tactical decision-making.
