The E.C.H.O. Visor (Electrosignetic Caphsronis Hectron Obenexer), was a high-tech signal visor created by a precise and complex three-fold combination of black market, stolen Imperial and Rebellion technology. It utilized the absolute peak of technology during its time, which also accounted for its rarity, complicated features, and especially its infamous expense. To ensure that it would never burn out or decrease in effectiveness, the E.C.H.O. Visor was energized by two small Artusian crystals located near the Visor's left and right temples.
