The Eco Seeker is a Precursor Artifact that has been watched by Duke Skyheed and the Aeropan people for some time. It is used to find large amounts of Eco. When it tracks Eco, it will open and point to the source. It's only appearance is in Jak and Daxter: The Lost Frontier, and doesn't appear very many times in the game. Keira is usually the only person who uses it, but Jak and Pheonix use the locations it gives to find Eco and defeat the Aeropan people.
 Type of Artifact
This is presumed to be a Precursor Artifact, due to the fact that it can track Eco. The appearance (resembling objects like Precursor Orbs and Precursor Temples) also leads people to believe that the Precursors created this object, unlike many of the things on the Brink of the World, where the Precursors seem to have little influence.
