Conquering long distances is a specialty of the Brunton Eterna 51mm objective lens binocular. The benefits of big glass are often overshadowed by an enormous weight—not a problem with the Eterna. Fully multi-coated optics optimize the Eterna's light transmission for bright views on cloudy days. The Eterna is waterproof, fogproof, and built to last. Brunton covers the Eterna with a limited lifetime warranty.
