A powerful tracking device that can be customized to fit any set of parameters: people, weapons, objects, and locations are some of the possibilities.
The R-Tracker is a portable tracking device. It appears in the Carrington Villa: Hostage One and Skedar Ruins: Battle Shrine missions in Perfect Dark, and a special version is also featured in the Crash Site mission.

There is also a version of the R-Tracker that locates secret weapons caches that can be obtained by using a cheat.

In all cases, when toggled it will show a small radar in the top right of the screen with icons representing the location of whatever object it is set for.
