"Agents of S.H.I.E.L.D. Episode 1.13: T.R.A.C.K.S."
During an undercover mission to follow an unknown package designed by Cybertek, Inc and delivered to Ian Quinn, Agent Melinda May used this pair of goggles to follow the tracks left by Cybertek Head of Security Carlo Mancini after stepping into ashes scattered by Agent Jemma Simmons. Agent May located the package, that appeared black in infrared vision due to it being laced with a tungsten polymer to avoid scanning.
