The TD-042EDMO, 3D Series 10x42mm High Definition Waterproof Binoculars with ED Glass (Mossy Oak Camouflage) is part of our 3D/ED Series Binocular line and combines dielectric prism coatings with ED glass. ED glass gives you the brightest, and clearest, high definition image possible. ED Glass reduces the amount of chromatic aberration that occurs as light passes through a binocular. Chromatic aberration presents itself as color fringes that appear around your viewing subject. Dielectric prism coatings greatly improve light transmission, brightness and provide clear, high contrast images that show accurate color reproduction. The Mossy Oak™ Armor makes the TD-042EDMO ideal for hunting. Rubberized armor coating makes this full-sized 3D/ED Series binocular rugged and shock proof. The body is nitrogen purged and O-ring sealed making them waterproof and fogproof. Extra long eye relief with twist down eyecups make this full-sized 3D/ED Series glass binocular perfect for eyeglass wearers. The precisely placed thumb grooves, “just right” texturing and all-over lightweight body ergonomics make the 3D/ED Series binoculars perfect for long hunts or any outdoor activities. * Warning – The case for this device contains magnets which can interfere with pacemakers and implantable cardioverter defibrillators (ICD’s).
