PVS-31 night vison Binocular Night Vision Device (BNVD) is a rugged, self-contained, compact & lightweight dual tube goggle. Ergonomic, low-profile binocular design provides operator with superior situational awareness and improved depth perception over single-tube systems.
KEY BENEFIT
Manual system gain and focus adjustments for custom image quality optimization
Lightweight ergonomic design reduces head-borne weight and decreases neck strain
Optional diopter lenses optimize operator preference for visual acuity
Rotating binocular design allows low profile against helmet when in stowed position and the option to use as a single monocular
Works with currently fielded dovetail helmet mounts
Auto OFF when stowed; resumes power when deployed
PVS31 night vision device has an ergonomic low-profile design and offers superior situational awareness compared to a single tube goggle. Working directly with input from Special Forces operators, the BNVD was designed to increase system resolution, significantly reduce head-borne weight and improve system center of gravity.
