Electro map

An electro map is a piece of technology from the cartoon portion of the Generation 1 continuity family.

The Golden Compass's poorer cousin.

An electro map is a device of Transformer design that Perceptor constructed. It works similarly to a human compass and allows the user to find their way in locations they were not aware of.

Fiction

The Transformers cartoon

During the Autobots' trip to repair a power generator, Rodimus Prime made use of Perceptor's electro map to find his way to their destination. Grimlock wanted to try the machine and took it from Rodimus, whereupon the Dinobot leader turned the arrow constantly in circles until it broke. Then he threw the device away. Grimlock's New Brain
