GSCI PVS-31C-MOD Image Intensified Night Vision Goggles
GSCI products are custom-made to order, current lead times are generally 2 to 3 weeks from receiving payment for your order until your device is ready to be dispatched by GSCI. Once your device has been dispatched we expect for you to receive your order within 1-week (UK & EU).
The new PVS-31C-MOD is a dual-tube goggle system with ergonomic design and improved functionality. It accommodates features such as a dedicated Instant-On-IR button 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. By customer's request, the unit can be equipped with Bayonet (PVS) or Dove-Tail style bracket.
Thanks to dual-tube design, PVS-31C-MOD delivers depth perception and allows using PVS-31C-MOD to operate various machines, boats etc., in addition to basic ground operations. A dual-tube night vision system has proved to be safer and more effective in low-light conditions compared to a “bi-ocular” system, commonly known as “PVS-7”, which is a “one lens-two eyes” type of NVD.
