The Tracking Syringe was a Yautja device notably used by Wolf in Gunnison, Colorado in 2004. The Syringe could collect Facehugger DNA samples which could then be injected into a Yautja's Wrist Gauntlet in order to to calibrate their Bio-Mask's Predator-Vision, enabling them to see Facehuggers and their tracks. The Tracking Syringe had a place to be stored in the Cleaner Case.
When Wolf departed for Gunnison, Colorado in 2004, he carried a Tracking Syringe in his Cleaner Case. When he discovered that Facehuggers had escaped their tubes aboard a crashed Scout Ship, Wolf collected a sample of Facehugger DNA from a smashed tube using a Tracking Syringe. After injecting it into his Wrist Gauntlet, he could see the Facehugger tracks in the surrounding environment and if they been on a host.
