Sensing Technique

This technique is used by sensors to detect someone's chakra. Using this jutsu, sensors can tell when enemies are approaching, and can easily track down targets.A good sensor can tell the difference between people and animals(as seen when Karin identifies Akamaru) The range of this jutsu varies between sensors.Sensing chakra is an ability that is also granted with the sage mode, because in this state a ninja(like Naruto or Jiraiya who are senjutsu users) can feel others unique natural chakra.
