This roof prism binocular is outfitted with Bak-4 prisms and fully multi-coated lenses that work in tandem with the ample 42mm aperture to produce bright, high contrast images.

It has a close focus of 2 meters, which is especially helpful when viewing nearby birds and wildlife, and an 8x magnification that delivers crisp details at shorter to mid-range distances and a wider field of view than a 10x model.

In addition to being waterproof and impervious to internal fogging, the binocular has an open bridge design that provides a sturdy grip even in wet weather conditions.

Each binocular comes with lens covers to protect the optics during storage and transit, a neck strap to make sure they are always at the ready and a storage case.
