The fact is that "dual tube" night vision optical systems have proven to be more effective and safe for low light conditions compared to a "pseudo binocular" system, commonly referred to the "PVS-7" model, which is a "one lens-two eyes" type of NVD.

The crucial issue in a modern military is "survivability" of a soldier. Depth perception of such a "dual tube" device allows using the set for operating various machines, boats etc., in addition to the basic ground operations. Therefore, PVS-31C is considered to be the most favourable night vision goggles in new procurements regardless of the higher cost compared to the "one tube" NVD.

Another added versatility is that PVS-31C can be de-assembled from dual bridge mount, enabling it to being used as two completely separate multi-purpose monoculars.

PVS-31C is high performance modular, multi-purpose night vision binoculars. Precisely and ruggedly built housing and optics meet or exceed military specifications. PVS-31C can be used as head gear, helmet mount assemblies for hands free use. Alternatively, the system can be used as hand-held binoculars with 2 pcs. of 3X or 5X lenses attached.

Device has a built-in short range Infrared Illuminator and is waterproof IP67, fully submersible.

PVS-31C works with two 3 volt CR123 lithium batteries or two AA type batteries. The device is compatible with most IR laser aiming and illuminating devices. PVS-31C is fully MIL-STD-810E compliant and ITAR-free, Canadian Made system.
