We developed the Cronus 12-36×50 ED to give you one of world’s best spotting scopes with brighter and clearer edge-to-edge detail. Whether you’re hunting above timberline in Alaska, or birding at sea level at Cape May, you will know every detail of your trophy before you take the shot or mark it off your life list. The Cronus product line has just about every feature you would put in a scope to make it the best you can get in its class. We designed the Cronus with Apochromatic system to give you images that have greater contrast, sharpness, and color definition. We included ED Glass that results in a clearer and sharper image. Our state of the art ESP (Enhance Spectral Prism) dielectric coating reflects 99% of the light through the prism assembly. Other design enhancements include BaK-4 prisms and our advanced fully multi-coated lenses that deliver flawless color fidelity, ultra-crisp images, and optimum light transmission. Finally we topped it off with our XPL lens coating that protects the exterior lenses from scratches, dust, and anything else mother nature throws at you.
