Outfitted with premium Hoya ED (Extra-low Dispersion) glass, Vanguard’s Endeavor ED II binoculars possess excellent edge-to-edge clarity and brightness. The optics are nitrogen purged to prevent fogging and the lightweight magnesium alloy body has been completely redesigned: It is now fully waterproof and shockproof, while being extremely comfortable and stable in the hand.
