Enhance your next hiking trip, birding expedition or weekend adventure with a National Geographic Excursion Series 10x42 binocular designed to deliver bright images filled with long distance details.

The optics in this versatile binocular consist of premium Bak-4 prisms and fully multi-coated lenses that maximize contrast. The optical elements are contained in a waterproof housing that is purged with an inert gas to prevent disruptive internal fogging. The binocular also offers a generous 42mm aperture that brings in lots of light for brilliant images even in lower light situations, a 10x magnification that is ideal for long distance targets and a close focus of 2 meters.

In addition to having a streamlined roof prism design that is less bulky than a traditional Porro option, the Excursion binoculars have an open bridge that promotes a steady grip even during longer observing sessions. Additional features include twist-up eyecups for a comfortable viewing and diopter adjustment for achieving proper focus for each eye. Each pair comes with lens covers to protect the optics during storage and transit, a neck strap to keep them close at hand and a storage case.
