Designed for serious glassing- with exceptional edge to edge clarity- sharp detail enhancement- ultra-clear brightness and true color representation. Whether you are on your annual hunt for whitetails on the family farm in Alabama- or filling your tag on an once in a lifetime Montana Big Horn- don't leave anything to chance. We designed these binoculars with our revolutionary E2ES lens system that gives you a flat field of view. We included Extra-Low Dispersion Glass lenses 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. We use a Magnesium chassis to reduce weight while keeping the chassis rugged to withstand the scrapes and bumps of constant use.
