Echolocation

Echolocation is the art and science of using sound to determine the distance and direction of something. The secret to echolocation is the use of sound to detect objects. These sounds can differ greatly, from bellows to signal frequencies. During the era of the Galactic Empire, the technology utilizing echolocation took another leap forward, with the creation of echolocation which could reveal invisibility or any sort by the siphoning of foreign signals. This was most realized with the creation of the E.C.H.O. Visor.
