Exceptional Orion Otter 10x42 Waterproof Roof Prism Binoculars are built to give you peak optical performance in almost any weather. These powerhouse daytime binoculars provide superb quality both inside and out!

These waterproof wonders are loaded with top-notch features and exquisite optics including 5-element eyepieces and 4-element water-repellant objective lenses to deliver great daytime views of birds, wildlife, scenery, and more, even in damp conditions. Otter 10x42 binoculars collect a good amount of light thanks to their substantial 42mm-diameter objective lenses, and they provide bright, crisply detailed views with a whopping 10-power magnification boost compared to unaided eyes.

Powerful Otter 10x42 Waterproof Roof Prism Binoculars are perfect for hunting, close-up studies of scenery and wildlife. These 10-power Otters deliver a wide and clear 6.4 field-of-view to your eyes for a pleasant 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 10x42 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 10x42 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.

You'll enjoy the Otter 10x42 binoculars' substantial 17mm eye relief, which allows you to keep your eyes at a comfortable distance from the eyepieces while seeing the entire field-of-view. 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.
