A device given to the Doctor by the Xerons after their planet had been liberated from the Morok Empire. It enabled the users to review any event in time and space on a large television-like screen. Vicki opted to see the Beatles perform, although she was unaware they played classical music, while Barbara Wright wanted to see Shakespeare at the court of Elizabeth I. Ian Chesterton chose to witness President Lincoln's Gettysburg address. However, the Doctor became alarmed when he saw the Daleks preparing a time machine similar to the TARDIS, by which means they planned to hunt him down.
