B1.2 - 8x42 / 10x42
The B.1.2 is an updated version of our popular flagship B.1 Binocular. We took the best features of a classic and improved upon our original binocular design with a wider field of view, improved coatings, a larger, wider Schmidt-Pechan prism, and packaged it in a lighter, more compact build that boasts excellent light transmission. This binocular is our recommended go-to for an all-purpose optic for hunting, birding, and general-purpose wildlife viewing. Made to handle most situations, the B.1.2 features superior low-light performance, tack-sharp edge-to-edge clarity, generous depth of field, and a silky focus mechanism.
The Maven B Series represents our elite line of optics, designed to fit your specific needs, delivered for a fraction of comparable binoculars’ cost, and stacks up with the most celebrated and expensive binoculars in the world. Our modern sportsman-inspired designs paired with the best available materials and state-of-the-art technology, create an uncompromising optic.
Includes neoprene neck strap, lens caps, and double-layered microfiber storage bag.
