See distant objects much closer through the Vanguard Endeavor 10 x 42 ED II Glass Binoculars. This pair features an Extra-low Dispersion (ED) glass, which works in conjunction with phase-corrected BaK4 prisms in order to eliminate chromatic aberrations. This is essential for getting a true color fidelity and enhanced contrast throughout the entire viewing field. The fully multi-coated, anti-reflection optics helps in improving light transmission for producing clear, bright images with greater low-light performance. These binoculars have a sturdy magnesium-alloy housing and a pebbled, rubberized protective housing armor that protect them from damage. Furthermore, these binoculars are O-ring-sealed and filled with nitrogen for water and fog resistance.
