Yes, there are two ways you can get a compass in the game, either for free by helping the Prapor or by buying it from the Jaeger. To receive it from the Prapor, you have to complete two quests – “Debut” and “Search mission.” Make sure that you have reached at least level 5 in the game before starting them, though. Eliminate five scavs at Customs and bring the Prapor two MP-133 shotguns. Then, help him to find his missing convoy and the location of the USEC camp. For your help, Prapor will give you a compass and some money. If for some reason you missed Prapor quests or don’t want to spend time on them, you can unlock the Jaeger’s store by completing the “Gunsmith Part 1” Mechanic’s quest.
