Bring the world closer without being weighed down by bulky binoculars with the Brunton ECHO® Zoom Monocular . This small, ergonomic pocket scope is built to fit snugly in your pocket or pack lid, serving as the perfect companion for backpackers, hunters, birdwatchers, and search-and-rescue teams. Whether you need to spot distant landmarks on a high-alpine trek or observe wildlife from a hidden blind, the ECHO® Zoom provides high-performance optics that you can deploy in a fraction of a second. Constructed with a rugged aluminum body , this monocular is built to handle the grit of the backcountry while protecting its internal alignment. The inclusion of a flexible, fold-down eyecup reduces distracting glare and provides a comfortable viewing experience, even for those wearing glasses. Boasting a close-focus capability of just 10 feet, it is equally adept at detailed near-distance tracking as it is at scanning the horizon. Complete with a protective storage case, a wrist lanyard, and a lens cleaning cloth, this highly portable scope ensures you never miss a detail on your next adventure.
