The 12x40 Predator Pro features Steiner's new PC5 Color Adjusted Transmission (CAT) lens coating that enhances brown and red colors against foliated backgrounds, making game subjects "pop" from their woodland environs. The 12x40 Predator Pro offers markedly brighter and crisper images, enhancing the binocular's effectiveness at dusk and dawn, or in poor weather or low light conditions. 10-year limited warranty.
