The Horizon Scanner is a futuristic set of binoculars, seen in the Air Base: Espionage and Crash Site: Confrontation missions, in Perfect Dark. It allows the player to see as far as one would be able to with a Sniper Rifle, but it serves little purpose in both of the missions it's featured in, as the Air Base: Espionage objectives are in close proximity, and multiple Sniper Rifles can be found in Crash Site: Confrontation.
