The Vortex Crossfire HD 8x42 is suitable for bird watching, hunting, traveling, sports, and more. The model has an HD optical system and the lenses have a special coating. This ensures you have a clear and sharp view. The binoculars also have a light intensity of 27. The 8x magnification brings distant objects close. You can watch animals at 1000m away with a field of view of 131m. And if you want to watch close objects, you can focus on them from 1.8m. Thanks to the O rings and gas filling, the binoculars are sealed from moist, dust, and dirt. There is a rubber protective layer around the casing which provides extra grip.
