Sensing Water Sphere

The Sensing Sphere is a technique utilised by multiple shinobi in a triangular formation and is used to monitor chakra signatures in particular locations. Know variants include ones made from sand and water.

Overview
Individuals or groups are represented as varying-sized bubbles or shockwaves 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.

Trivia

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