The Son'a deployed several isolinear tag drones upon the Ba'ku, in an attempt to relocate them while the Son'a harvested their planet's metaphasic radiation.

The drones, once airborne, are fully automated. Their isolinear tags allow for a ship in orbit to easily lock transporters on subjects en masse, especially when transporter inhibitors are in place, as they were when Picard and crew used such inhibitors to protect the Ba'ku.

Several drones managed to successfully lock onto their subjects, but several drones were also destroyed by the Enterprise crew during both phaser and hand-to-hand combat.
