Based on a regular anomalous activity scanner, this device is combined with a limited range mutant detection sensor and a recording component for storage of results. The device is equipped with an automatic deactivation switch that is fired when a certain amount of data has been collected.
― In-game description
The Mutant detection scanner is a mission item in S.T.A.L.K.E.R.: Call of Pripyat.
Description[]
This item is given to the player by Ozersky after taking his mission Hypothesis. It must be placed in the middle of the Bitumen Anomaly. Once placed, seven snorks will appear and jump into the anomaly, and start walking around in the vicinity of the detector (unless the player is close by, in which case they may attack the player instead).
After a few minutes or after killing all the snorks, the detector must be retrieved and taken back to Ozersky to complete the mission.
