A contact type of sensing. By dispersing a significant quantity of specialized sand in a targeted area, the user is able to discern the presence of any enemy coming into direct contact with the sand in question. If this substance is spread upon appropriately textured and coloured terrain, it becomes almost impossible to detect by simply its appearance alone, aptly demonstrated when it managed to catch even the Second Tsuchikage off guard when the ability was introduced.
