The Bushnell 10x25 H2O Binocular eliminates all the worries of water damage, and features nitrogen purging for total fogproof and waterproof protection. It provides a great grip when wet thanks to its special rubber armor with ridges, and the center focus dial gets where you want to go in a hurry. This is a compact 'twin bridge' folding roof prism unit, with a wide 6.3° viewing angle for a 10x model, and it can fit in a shirt breast pocket.
