Homing device



A homing device, also called a tracking device; was a type of gadget that was used for tracking the movement of someone.

Typically they were equipped with a radio transmitter, which could be placed on whatever it was someone was trying to keep tabs on, and then the radio receiver was used to follow the radio signal coming from the radio transmitter, thus leading whoever planted it on that someone directly to their target.

Batman had such gadgetry in his Bat-Belt. Robin also had such technology in his Utility Belt as well.
