Switching is easy. Leupold® Golden Ring® 10/17x 42mm Switch/Power™ Binoculars offer the kind of performance you expect, plus unique features you won't find in any other binocular. It's like having two binoculars in one. Switch/Power technology features an easy-to-use switch near the focus dial that allows you to instantly and fully change the magnification. This is not zoom; you go from 10x to 17x smoothly and instantly.
These binoculars are not only small and lightweight, but they are also tough, waterproof, fog-proof, and wilderness-ready. Well-designed and built solid, they present bright, sharp sight pictures. Leupold's signature brown armor coating ensures that the binoculars will withstand even the most rugged conditions.
With phase-coated roof prisms and Leupold's exclusive Index Matched Lens System - each lens coating is matched specifically to the type of glass and the lens placement in the binocular - the binoculars offer a standard of brightness, clarity, and color fidelity like you have never seen before. Full lifetime guarantee.
From humble immigrant beginnings, Leupold grew, based on a promise of quality, to become a classic American company. In 1907, Fred Leupold set up a one-man shop at 5th and Oak streets in Portland, Ore., to repair surveying equipment. He was joined by his brother-in-law, Adam Voelpel, and later by inventor John Cyprian Stevens, and the foundations for a century of success were in place.
During Leupold's second half-century, the company has focused heavily on the sports optics business. Leupold's presence in the hunting and shooting market expands, and finally dominates, with innovative optics and features that are now legendary among hunters, shooters, and outdoors enthusiasts. Many of the industry's standards - nitrogen waterproofing, the Duplex® reticle, and more - are Leupold creations.
