Remote Beacon

The Remote Beacon is a device disguised as a common rock frequently used by S.H.I.E.L.D. Agents on covert missions to covertly signal HQ.

One of these beacons was used by Agent Grant Ward during their mission to disable the Overkill Device. Once Agent Leo Fitz finished disabling the weapon, Agent Ward triggered the beacon, informing Agent Victoria Hand that their mission had been successful.
