Geomapper module

The Geomapper Module is a special item that can be received from Reilly after completing the Reilly's Rangers (quest) and taking the unmarked quest Geomapping with Reilly. The device downloads data about any world map markers you find and have found from your Pip-Boy 3000. This data can be downloaded by Reilly at the Ranger Compound who in turn will pay 30 caps per location found. It will also count the locations you have already discovered before receiving it, and you don't have to carry it around - just get it out of your house locker when ready to visit Reilly again, and she'll pay for any new locations.

This item can be replaced by Reilly (only in pc version) if you drop or sell it.
