Arthron

The Kanohi Arthron is the Mask of Sonar. It allows the user to sense the movements of objects through echoes, like something moving in the water. This mask can detect invisible beings, so in theory, it could see someone using a Huna or a Volitak. It did not identify details about the object or being.
