CEDRUS StimTracker Duo (base unit only) 
The StimTracker from Cedrus allows researchers to eliminate timing delays caused by computer operating systems or monitor graphics cards in data analysis. It uses light sensors to precisely detect stimuli changes and writes this information as time stamps (event markers) in EEG and eye tracking data. The common timestamps can then be used for easy multichannel synchronization and analysis.
The StimTracker is compatible with the iMotions EEG and Screen-based Eye Tracking Modules.
