New day to night vision conversion system

NIVISYS Industries announces a Gen. III day to night-vision conversion system that accurately works at real world tactical speed! 
 
What it does:  NIVISYS Industries a NEW state of the art clip-on night vision unit.  Known by model number NSV-80 simply, quickly and accurately clips onto the 1913 Picatinny rail in front of a telescopic sight to turn a daylight system into a night fighting system.  But wait, it gets better!
 
Why It's Better:  The NSV-80 (night vision sight) does not require operators to have error prone separate night and day zeros on their telescopic sights.  The NSV-80 simply mounts in front of most telescopic sights via a quick-detach Picatinny compatible clip on mount.  While not always required, the NSV-80 also features a rear rubber seal (Litegard) that fits between the scope's objective lens (or sunshade) and the NSV-80 to eliminate or limit peripheral light. 
 
No Fiddle Factor:  The NSV-80 internal optics makes an accurate full-field view possible even if it is NOT in alignment with the telescopic sight's objective lens.  In other words, if the reticle is in view, the NSV-80 reticle is still on target without further adjustment.  No need for potential zeroing errors when converting from day to night operations.  NIVISYS' NSV-80 provides a clear and precise parallax-proof conversion from day optics to dark time without any scope adjustments.   
 
Zeiss Optics, that's why!  The optics system and housing of the NSV-80 is made by Zeiss Optics.  Then the unit is sent to the folks at NIVISYS where their superior-quality generation III electronics and intensifier tube are installed.  Obviously Zeiss was very selective with whom they partnered with and they choose to partner exclusively with NIVISYS on this outstanding user friendly no mess no fuss system.
 
The unit is so ergonomically friendly that it can be mounted and operated in total darkness (no need for any red flashlights, etc.) and even with the operator wearing gloves.  Simply clip on and turn on.
