When you want the best optical performance - rain or shine - grab a pair of Orion Otter ED binoculars and prepare to be impressed! Waterproof Otter ED 10x42 binoculars feature fully multi-coated ED glass optics and phase-coated BAK-4 roof prisms to deliver exceptionally clear, true-color views in any weather.

In binoculars without ED optics, light is scattered as it passes through the lenses and prisms, which reduces clarity and causes color fringing, resulting in an undesirable viewing experience. The specially made extra-low dispersion glass found in our Otter ED binoculars eliminate color fringing by significantly reducing light scattering so you can enjoy true-color performance and crystal-clear views.

Rugged Orion Otter ED 10x42 binoculars are built with a strong, magnesium alloy body with rubberized armoring for a comfortable grip. Each barrel is held rigidly in-place thanks to the open-hinge binocular design which helps maintain optical alignment even in rough conditions. A super-smooth center focus wheel makes it easy to dial-in crisp and clear views.

The 10x42 Otter ED binocular boasts a 5.6 field-of-view perfect for powerful scanning at 10x magnification. These Otter ED binoculars can focus on objects as close as 6.6' away, which is especially useful while hiking and birdwatching.

Compact Otter ED binoculars won't take up a lot of space with their 6.5"x5" size, and a clamshell-style carry case is included. Tethered objective lenscaps, a single-piece eyepiece cap and wide neckstrap are also included.
