Bushnell H2O 2 10x42 Roof Prism Binoculars

On a rainy coastal hike, you spot a distant sailboat and raise the Bushnell H2O 2 10x42 to your eyes. The fully multi-coated BaK-4 roof prisms deliver a bright, crisp image with true-to-life colour, while the 10x magnification brings the vessel into sharp detail. The non-slip rubber armour provides a secure grip even with wet hands, and the waterproof, fogproof construction shrugs off the spray. Whether you're scanning the shoreline for birds or tracking a moving target, the smooth focus wheel and generous 17 mm eye relief keep the view comfortable for eyeglass wearers.
