Konus Emperor 10X42 Binocular Waterproof Green
The Konus Emperor 10X42 binocular delivers the optical clarity and durability serious glassing demands, whether you're glassing distant ridges for elk, scanning open water, or picking apart brushy terrain for whitetail. Built with BAK-4 prisms and phase correction coating, these waterproof binoculars are engineered to gather and focus light with exceptional brightness and contrast—especially valuable when you need to resolve fine details at distance or in lower light. The nitrogen-purged, sealed body shrugs off rain, spray, and humidity without fogging, so you can hunt or bird-watch from dawn through wet conditions without hesitation.
At 10x magnification and 42mm objective diameter, the Emperor strikes a practical balance for most hunting and field applications. The wide-angle eyepieces and extra-long eye relief mean you'll get a full field of view even with a hat brim or rangefinder in the way, while the twist-up eyecups let you dial in your ideal eye position. The green finish is both functional and built to blend into natural settings. This is a binocular built to earn its place in your pack or truck—tough enough to handle a season's worth of field work, clear enough to make the critical shot-or-pass decision count.
Konus engineered the Emperor for hunters, anglers, and outdoor enthusiasts who need dependable glass without compromise. The combination of phase-corrected BAK-4 optics and sealed construction means you get the image fidelity and durability to trust in the field, season after season.
