For binoculars that rival the most expensive European brands at a fraction of the cost, you can't beat the new Meade Glacier Binoculars. These rugged binoculars have multi-coated lenses and phase-coated roof prisms that combine to give you views that are exceptionally bright, crisp, and high in contrast. The high-tech phase coatings alone increase prism reflectivity by 8%. Glacier Binoculars give you on average an extra hour of visibility at dawn and dusk compared to standard binoculars. They are nitrogen purged for fogproof viewing and O-ring sealed for waterproof protection. Glacier Binoculars, As bright as binoculars can get.
