The Maven B.4 Binocular was designed to pick up where the B.2 leaves off and is built as an alternative to low to mid-powered spotting scopes. Built with a larger than typical ocular eyepiece, the B.4 offers a broader viewing area for when dimly-lit situations call for extra light and extra magnification. The B.4 is a large objective optic and is our recommended optic for hunters and birders who prefer to glass with a tripod setup.    

 The B.4 also features tack-sharp edge-to-edge clarity, generous depth of field, and a silky focus mechanism. Additionally, the split frame design gives this larger objective optic a lighter weight chassis all while maintaining durability.

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.
