A Traveler armband is a piece of technology created by a race of technologically advanced Pegasus Humans known as the Travelers. The armbands are around the same size as the wearer's forearm from his or her wrist to his or her elbow. (SGA: "Travelers")
The armbands have two main functions;
- They serve as communication devices, allowing the wearer to talk to another individual wearing the armband from a certain distance.
- They contain radiation detectors, which beep when dangerous levels are detected.
