Offering exceptional quality inside and out, extraordinary Orion Otter 8x42 Waterproof Roof Prism Binoculars are built to give you peak optical performance in almost any weather.

Loaded with top-notch features and exquisite optics, these 8x42 Otters have 5-element eyepieces and 4-element water-repellant objective lenses to deliver great daytime views of birds, wildlife, scenery, and more in even damp and dreary conditions. Light collected by the substantial 42mm-diameter objective lenses provide bright, superbly detailed views with an 8-power magnification boost.

Perfect for birding, Otter 8x42 Waterproof Roof Prism Binoculars boast a wide, wonderfully clear 7.4 field-of-view. Otter binocular optics are fully multi-coated with anti-reflection coatings for clear and sharp daytime views that are delightfully rich in contrast. Waterproof Otter 8x42 binoculars feature top-quality BAK-4 roof prisms, which help transmit the maximum amount of light to your eyes and also help keep the binocular conveniently sized for daytime hikes and other outdoor adventures where a binocular can be handy. Hardened prism mountings inside the Otter 8x42 significantly help to retain collimation and prism alignment better than non-hardened mountings, so these rugged Otters are ideal for use in the outdoors. All these great optical features come together in an elegant and attractive magnesium body that is both lightweight and strong with a comfortable textured grip.

Eyeglass wearers will enjoy the Otter 8x42's long 19mm eye relief, which allows for comfortable use while wearing corrective lenses. These binoculars have a tremendous close-focus capability which allows close-up study of birds, butterflies and more from just 6.5 feet away. Includes neck strap, lens caps, and a hard carry case with strap. Weighs 1.6 lbs.
