You will be directed to Boroda, who will reward the protagonist with a new generation Svarog detector. When you leave the territory of the dry cargo ship, Sych will contact by radio and ask you to enter. Sleep for 24 hours and leave the stalker base.
Now you will need to return to Sych and report that you have taken the detectors. Inside, talk to Novikov and give him the detectors. When you have at least 3 detectors on your hands, then go to the scientists' bunker in the Jupiter sector. This amount will open the achievement, thanks to which new items will appear in the store, and after a while Sych himself will start selling Veles detectors for 2,000 rubles each. On the other hand, there is an opportunity to earn 100,000 rubles by selling artifacts to Boroda. The last detector, with a little bit of luck, can be found during a search of one of the dead.
The third can be obtained from Herman as a reward for completing the quest 'Search of the anomaly' on 'Jupiter' or bought from a Hawaiian on 'Yanov' for 2000 rubles. To do this, you need to visit the dedicated area 'Kopachi' (by the way, you will be there as part of the 'Kopachi' quest with Uncle Yar). The second is in the excavator cabin on the Jupiter. The first one can be obtained after completing the mission 'The disappearance of stalkers'. Where to get: Owl after completing Lair of Bloodsuckers.
