With powerful magnification, multi-coated glass, and a housing designed to withstand the elements, the 10x25 Solo Monocular from Vortex is suited to birding, hiking, hunting, travel, sightseeing, concerts, sports, theater – anywhere you want a good look at distant details. For that matter, with its close-focus distance of just 16.4 feet, the Solo gives you a good look at nearby objects, too. Its rubber-armored housing is O-ring sealed to keep out water and dust, and purged with nitrogen to prevent internal fogging no matter the conditions. The twist-up eyecup and 15mm eye relief make this monocular comfortable for people who wear eyeglasses. And at 4.4 x 2.2" and less than 6 ounces, it's easy to pack in a pocket, purse, bag, or glove box.
