BNVD 1431 MK2 OMNI 8

The BNVD 1431 Omni 8 is the same housing as the Omni 7 version with the next generation of image intensifier installed.  It offers the versatility and durability of vastly more expensive systems like the PVS-31, and this is just like its less expensive brother.


What Is The BNVD 1431 MK2 Omni8?

The BNVD-1431-Omni8 is a binocular night vision device (BNVD) that consists of Omni 8 Image Intensifier Tubes, Mil-Spec Optics, and a housing made by the Argus Company then optimized here in the USA.

The American Image Intensifiers are 3rd Generation from the Omni 8 contract, so this means you get a tube with all the latest characteristics, including a gated power supply. You receive most of the performance as well, and the green phosphor output is the main difference between these tubes and ones costing much more.

The standard Mil-Spec lenses meet/exceed the requirements for military use, and you can upgrade to Carson Optics lenses if desired. They are the standard by which everyone judges systems.

What Are The 1431 MK2 Omni8’s System Specifications?
