Vanguard Endeavor ED II 8420 - Binoculars ED 8x42

the 8x42 Endeavor ED II Binocular from VANGUARD Optics features extra-low dispersion (ED) crystals and corrected BaK4 phase correctors that work together to virtually eliminate chromatic aberration, which produces images with true color fidelity across the field of view and enhanced contrast. Complementing the glass and prisms are fully multilayer anti-reflective optics that enhance light transmission for bright, clear images, with increased low-light performance. An open bridge design helps reduce weight without sacrificing strength, and provides a large surface area to hold. Rubber armor with boulders helps protect against falls and impacts and helps provide a non-slip grip. Designed to last, the lightweight magnesium alloy housing is filled with nitrogen and sealed with O-ring to provide water resistance and fog test, and the 3-stage rotating dark circles provide personalized eye relief to wear with or without eyes-to-wear.
