The Kanohi Arthron was the Mask of Sonar. It gave its user the power to sense the movements and positions of targets through echolocation. This mask power could detect beings, but could not identify details about the target. The powers of this mask also allowed its user to perceive Huna and Volitak users and see through illusions. An Arthron is always on at a low level.
Example Usage
