Curioscanner
From Tardis Wiki, the free Doctor Who reference
The curioscanner was a sonic device in the possession of the Doctor, which could detect exoplanetary energy.
In 1651, the Twelfth Doctor attempted to use it to find the Eyes of Hades on Earth, having tracked it from across the galaxy. He eventually found the Eyes, with the assistance of Ashildr. (TV: The Woman Who Lived)
