The scanner monitored the bio-electric signatures of the crew in the event they were separated from the pod. In 2367, Geordi La Forge modified the myographic scanner of an escape pod of the Arcos, stranded on Turkana IV, and installed a booster on the device that would relay its signals directly to the USS Enterprise-D. By doing that, the survivors of the Arcos that were abducted by the Turkana IV Alliance, one of the factions of Turkana IV, could be located.
