Keeping in touch with headquarters
Communicators are quest an equippable item that appears in . They were developed by Sonic Chronicles: The Dark Brotherhood Dr. Eggman, responding only to a special frequency used by the doctor.
Sometime after Eggman was presumed dead,
Marauder Scouts used these communicators to keep in touch with their base. In Sonic Chronicles: The Dark Brotherhood, when Sonic and his friends were searching for Knuckles in Eggman's old hideouts, they found a communicator in each of the four abandoned hideouts. After the team had found Knuckles, Tails rewired the four communicators they had found, reversing them in order to detect the special frequency they used to operate. The resulting tracker was the Eggman Detector, which was used to find Eggman's secret base in Green Hill Zone

↑ Tails, at the beginning of
Chapter 3: "These communicators we found are old Eggman technology. They were made to respond only to a special frequency Eggman used."
