Electromagnetic Perception Technique

By concentrating ones chakra with the necessary hand seal the user is able to produce a low frequency electromagnetic field around themselves in order to sense the presence of anything that disturbs the field, like chakra. It seems to require a higher amount of concentration at greater distances and while it cannot sense things that mask their chakra it can tell that something is being hidden. Shirokaze was able to discern a persons location, chakra nature, and kekkei genakei with this technique, but it require him to concentrate harder than usual. This technique can also be used to help a person track the movements of enemies in a combat situation, but the limits of this ability have yet to be tested as of yet.
