When Agent Felix Blake was critically injured by Deathlok, Blake put a tracker on him which led Coulson's Team, Garrett's Team, and a raiding squad to an abandoned race track in Pensacola, Florida. There, Fitz used the Golden Retrievers as advance scouts. Through them Skye saw the cybernetic enhancements of Deathlok and ultimately found Thomas Nash.
The Golden Retrievers, like their forensic evidence collection counterparts, the D.W.A.R.F.s, come in a set of eight, and are tracking drones designed for autonomous functionality while sending their retrieved information back to their operator. They launch from their case and disperse in different directions while searching for their programmed target, scanning for visual data under different wavelengths, such as infrared and ultraviolet.
When the retrievers find their target, the location information is immediately sent back to the unit's operator.
