Single Hinge Binoculars
Single hinge binoculars are a category of fixed hinge design binoculars with centre focus and fold-down eyecups. They include both roof prism and porro prism models. Roof prism versions use BK7 prisms and are not nitrogen filled. Porro prism versions offer optional BK7 or BAK4 prisms and are also not nitrogen filled. All models are daily-life water resistant only and are not rated IPX7. They are built for brands that need cost-effective, entry-level optics with standard features and simple customisation options.
