Wrist Communicator

From Power Rangers Universe

The Wrist Communicator is a watch-like device used by the Mighty Morphin Power Rangers to communicate with one another, their base of operations, and for teleportation usage as well. They were created by Billy Cranston once the Power Rangers came to be. The communicators made a sound that resembled the Power Rangers Theme Song when receiving an incoming transmission. The last team to be shown using the communicators were the Space Rangers, though they generally used their morphers to communicate with each other.

Tommy's son in A Season To Remember was shown with a communicator. Jason still had his in Forever Red.
