Sensing Water Sphere

This sphere, made of water, can be used to monitor chakra signatures in a given area. Individuals or groups are represented as varying-sized bubbles within the sphere, with larger chakra signatures having larger bubbles. The sphere itself is not a great form of detection and needs on-the-field reports to locate targets that should be kept track of. When linked with a Sensing Barrier, this imprecision is mitigated somewhat.

In the anime, a group of Suna shinobi used a variation of this technique, using sand as a medium instead of water.

Trivia

 * The name of this technique is derived from its Water Release version's name, which was provided in the fourth databook.
