Built on the foundation of the award-winning B.2 binocular, the large objective B.5 features a small/lighter magnesium frame and Abbe-Koenig prism and is paired with the very same fluorite glass that’s featured in our S Series Spotting Scopes. In both 15x and 18x options, the B.5 is our most powerful binocular and the fluorite glass is a step above ED glass of similar-sized optics. One of the most modern optical systems on the market, this purpose-built binocular is designed to extend your range for those who require increased magnification and the ability to discern detail during those critical low-light periods when covering big, open country. The B.5 is our recommended rig for those who are looking to step up their magnification range, but prefer a lightweight system when carrying a spotting scope is out of the question.
The B.5 also features tack-sharp edge-to-edge clarity, crystal clear glass, considerable eye relief, 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’ costs and stacks up with the most celebrated and expensive binoculars in the world. Whether you choose a stock color unit or configure your own custom-built optic, our modern sportsman-inspired designs are paired with the best available materials and state of the art technology to create an uncompromising optic.
Includes neoprene neck strap, lens caps and double-layered microfiber storage bag. -
