The Konus Emperor 10x42 WA Binoculars have BaK-4 prisms with Phase Correction. This is an advanced coating technique that will force the light beams back into phase, thus improving the image definition and contrast and creating a sharper view, especially noticeable when observing fine details.
All Konus spotting scopes, binoculars, or other optical products come with a Two Year Replacement Warranty against manufacturer defects. If you encounter a manufacturer’s defect on any of these products, simply send it to us for inspection and we will replace it. All warranty returns should be put in a shippable box, please include a note explaining the problem, your proof of purchase, return address (street address only, no P.O. Boxes) and a phone number. We will make every effort to replace the item with a like item. However, in the event your product is discontinued or out of stock, we will send you a like item of equal value.
