The 8x42 US Army Binoculars from Bower utilize BAK 4 roof prisms with anti-reflection multicoated optics to create images that are clear and bright. They are waterproof, so users can bring them on the water with confidence, and with a comfortable 8x magnification and wide angle 56° apparent field of view, subjects are easy to see, identify, and track with less noticeable shake than with higher-power binoculars. This wide viewing angle reduces wave-action discomfort at sea, and provides expansive views on land. Non-slip rubber armoring helps maintain a firm grip on the binoculars, while the twist-up eyecups make them comfortable to use with or without eyewear.
