GNV7 series are also known as PVS7 night vision goggles were developed to meet military and law enforcement requirements for surveillance at night. This high-performance device is a reasonable alternative at a lower cost to the majority-tor, IR” on” and low battery indicators, excess light exposure cut-off sensor and many other features.
The model is assembled with the highest quality Image Intensifier Tube Generation 2+, power supply with built-in bright flash protection (with automatic brightness gain regulation). The unit may be combined with 3x, 4x, 5x,7x or 8x magnifier lenses to further extend the viewing capability.
1. Night vision goggles can be head-strap mounted for hands free operation when used with a mask. Lightweight and comfort mask allows to adjust goggles to eyes position. Flip-flop mechanism assures easy unobstructed vision.
2. Operating mode switch and batteries compartment cover are easy to use even when operating in gloves.
3. Angle of IR illumination totally assures a field of view (controlled under assembling).
4. The goggles are performed as corrosion-proof.
5. Low battery indicator.
6. «IR-on» indicator.
