GSCI PVS-31C-MOD Dual-Tube Night Vision Goggles

Regular price $9,100.00 Sale

The GSCI PVS-31C-MOD is the modified and modernized dual-tube night vision binocular system from GSCI.

Since its first introduction back in 2014 PVS-31C until now has been widely regarded as a highly versatile, reliable and easy-to-operate unit. While retaining all features that users valued in the GSCI PVS-31C, the new GSCI PVS-31C-MOD adds in more ergonomic design coupled with improved functionality. It now accommodates more features such as a dedicated Instant-On-IR button: this enables to quickly and momentarily engage IR illuminator without having to operate the switch. The connector located at the front of the unit is used to supply power to the unit from almost any power source: external battery pack, USB power bank, 12V car socket and so on.

These and many other options bring the GSCI PVS-31C-MOD to a new level in performance, functionality and value.
