Designed and engineered to perform comfortably in the harshest conditions, Crossover Binoculars from BARSKA bring exceptional optic clarity together with a rugged, ergonomic design well suited to any active endeavor. The Crossover Binoculars are O-ring sealed for 100 percent waterproof protection so that you can use them in any weather. In addition, the binoculars are dry nitrogen-purged and sealed to protect the optics from fogging, clouding, and moisture damage. The binoculars have a 30-millimeter objective lens with 8x magnification delivered through fully multi-coated BAK-4 prisms that maximize light transmission for exceptionally crisp, clear, and bright images. Made for comfortable use wherever the adventure takes you, the binoculars boast twist-up eyecups, a right eye diopter, and a large center focus knob that makes image acquisition quick, easy, and comfortable. Finally, no matter where you are, the Crossovers will stand up to the environment thanks to rugged shock-absorbing rubber armor and a non-slip and ergonomic design for a secure grip. Backed by a limited lifetime warranty from Barska and coming complete with a carrying case, neck strap, and lens cloth, the Crossover Binoculars are a great choice for any outdoors adventurer.
