Elite Grade Weapon Sight TWS-3100-64

TWS-3100-64 is a series of high-performance thermal weapon sights for long-range engagements. It boasts “fast” 100mm objective lens paired to high-sensitivity FPA and together with the GSCI proprietary image enhancement solutions deliver staggering detection figure of 4,500 metres. TWS-3100-64 is manufactured in Canada according to strict military standards. Its body is made out of hard-anodized, high-strength aircraft grade aluminum to ensure maximum durability. TWS-3100-64 undoubtedly dominates other high-performance weapon-mountable thermal imaging systems on the global arena.


Like in all GSCI Thermal Systems, Non-Uniformity Correction (NUC, Calibration) of FPA is performed automatically, instantly and continuously to deliver crisp and highest image quality at all times. Auto-NUC technology results in no “clicks”, no interruptions in device’s operation. User is not distracted to perform any FPA calibrations whatsoever.

The system can be equipped with 50mm f/1.0 objective lens to improve user's situational awareness (Model: TWS-3050)


The device comes with a high-performance 640x480 thermal detector (FPA) running at 50Hz.
