Sensing is a skill used by sensor type shinobi to detect chakra. Using this technique, sensors can easily detect, and track down targets. The range of this technique varies between sensors.
Trivia
- Throughout the series, various characters have commented on the feel of chakra and similar comments regarding the ability to sense high, foul or potent levels of chakra a little, leading to the possibility that chakra sensing is merely a more refined version of this by either teaching or being simply born more "sensitive".[1][2][3][4]
