DISCOVERYOPT LHD-NV 3-12×44 scope has the best in class ANDC (Advanced Night and Day compatible) coating(wavelength 400-900) to enhance the clarity and performance of both the daytime need and also the performance with the Night vision(requires 850 wavelengths) add-on. In contrast, the conventional scope has a lens coating that would only be optimized during the daytime(400-700 on average). It works better with our NV001.
