B-Series Binoculars

Performance Is Not Negotiable. The Rest is Up To You.
What are you looking for? Your daughter’s first elk? The next bird on your life list? The last duck in your bag limit? Your quest is your own. And your opportunities are too valuable to compromise with substandard tools. Introducing the B Series Binoculars – elite optics, customized to fit your specific needs, delivered for a fraction of comparable binoculars’ costs.

Maybe the neighbor needs a German accent to tip him off to quality. You know quality when you see it. Superior low-light performance, tack-sharp edge-to-edge clarity, generous depth of field, silky focus mechanism – the B Series stacks up with the most celebrated and expensive binoculars in the world… bar none. If, after putting a demo set through its paces, you disagree send them back, no questions asked. If, after building your own, they fail your son 30 years from now, he can send them back too. We’ll stand behind a Maven as long as it bears our name.

It is a faith born of relationships and experience. Our engineering and manufacturing partner has built precision optical equipment, for the world’s most discerning clientele, since 1950. They’ve paired our modern sportsman inspired designs with the best available materials and state of the art technology to create four uncompromising chassis – the full-frame B1, enhanced B2, compact B3, and the large objective B4. You select a body, then apply your own experience, customizing a dozen elements until the instrument is tailored precisely to your preferences.

The product of our collaboration – designer, engineer and user – is finished stateside and delivered directly to you, bypassing the middleman and his hefty mark-up. The result is an heirloom quality binocular and a whole new way of seeing the world.

You are a Maven. Your vision is unique. It deserves a binocular to match.
