Hikers, nature lovers and anyone on the hunt for adventure will be well-prepared with this binocular, which is waterproof and purged with an inert gas to create a fog proof internal environment.

In addition to these high performance features, this binocular delivers optically with superior Bak-4 prisms and fully multi-coated lenses that generate bright images with excellent contrast, colour and clarity. The 42mm aperture has ample light-gathering capability and the 10x magnification reveals stunning details even at long distances. Twist-up eyecups and a 16.9mm eye relief maximizes field of view and provides a comfortable viewing experience for eyeglass wearers.
