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.

Maven: Crafted for the Outdoors
Mountain Town Roots
Maven started in a mountain town, driven by folks who'd rather be out hunting or hiking than chasing corporate profits. Their optics are made for people like you: hunters, birdwatchers, anyone who trusts their gear to make every moment in the wild count. It's honest craftsmanship from a team that shares your passion for the outdoors.
Top Quality Craftsmanship
Maven skips the retail middleman and those 15-30% markups that jack up prices in stores. By selling direct, they focus on what matters: top-grade Japanese glass and materials built to handle the toughest conditions, not cheapened to fit a retailer's price tag. You get optics designed to perform, shipped right from their workshop to your door.

As Maven's Australian supplier, The Modern Hunter is right here, living the same outdoor life you do. Call us up, and you'll talk to a real person who knows Maven's gear and Australia's rugged terrain inside out. We're ready to help you pick the perfect optics for your next adventure, with the kind of service you'd expect from a mate.
