to hone in on persons or ghosts
The GeeBeeper was a homing beacon device built into Ghost Buggy. It came equiped with a viewscreen on which the location of the item or person it was set to find would be broadcast. Senior Ghostbusters Jake Kong and Eddie Spenser used the GeeBeeper to find their lost sons after Jake Kong Jr., Eddie Spenser Jr. and Tracy the Gorilla had been turned into five-year olds by Sassella the Witch on Halloween night 1986.
The GeeBeeper was first used in the episode Back To The Past.
