The 8x42 H20 Porro Binocular from Bushnell delivers a fogproof housing and rubber armoring textured with soft ridges to maintain grip. This blue Porro prism binocular offers less light loss and greater depth of field than comparable roof prism designs. A multi-coated lens system and high-transmission BAK4 prism glass allow these weather-sealed glasses to display clear and bright images that are crisp with detail.
