Within the world of Naruto, Shinobi possess a wide array of impressive skills developed through training and natural talents. Each hidden village cultivates warriors with jutsu techniques specialized for its environment and philosophy. However, one often underestimated yet strategically important talent lies in the naturally occurring ability to sense chakra signatures without sight. Known as "Sensor types," these perceptive shinobi play a crucial role through their skill in covertly detecting others' chakra, even over vast distances. While anyone can sense powerful releases of chakra, sensor types can actively perceive it at will by concentrating their own chakra.
