The Vanguard 10x42 VEO ED Binoculars address the particular demands of hunters, birders, and outdoor enthusiasts by delivering bright high-contrast images with accurate true-to-life color and crisp clarity even when observing from long distances. To achieve this optical performance, these binoculars feature anti-reflection fully multi-coated extra-low dispersion (ED) glass with phase-correcting coatings on the BAK4 roof prisms. A wide apparent angle of view not only presents an immersive observational experience to complement the impressive optical performance, it also helps to minimize the distracting handshake that is common when holding high-power optics such as this. Designed to stand up to a lifetime of outdoor use, their chassis is made of a lightweight and durable composite material that is also corrosion resistant to make it ideal for boaters. The optical tubes are waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions. Vanguard includes tethered front and rear lens caps to add a layer of protection in the field, with the ability to quickly react to glassing opportunities without fear of losing the caps.
