Rangefinder/Legends

A rangefinder is a device that someone can wear in their helmet, or mount on their blaster, allowing them to zoom in on people and see their range, size, speed, and species. It is also used in Electrobinoculars, allowing the user to see across the battlefield. They also function to lock on to a person and enable the user to see them through walls until they lock off the person. Many military factions have adopted this technology to help them on the battlefield, such as the Trandoshan mercenary group and the Grand Army of the Republic.
