Maven B2 11x45

• Abbe-Koenig prism system: This prism design is chosen for strong light transmission and efficient low-light performance, helping the image stay bright and usable at dawn, dusk, and in shaded woodland.
• 11x45 configuration: The combination of 11x magnification and a 45.00 mm objective gives more reach than a typical 10x binocular while keeping enough exit pupil for steady observation in mixed light.
• Field flattener and ED glass design: The B2 platform is built for a sharp, high-contrast image with better edge definition, which makes long glassing sessions less tiring and helps with detail recognition at distance.
• Magnesium chassis: A magnesium body keeps the binocular strong without unnecessary bulk, so it handles hard field use while remaining practical for all-day carry.
• Waterproof, fogproof construction: Nitrogen filling and sealed construction help the binocular stay clear when weather changes, when moving between temperatures, or when glassing in wet conditions.

About the Maven B2 Series

The Maven B2 Series sits in Maven’s elite B Series and is built for users who place a premium on image quality in difficult light. This family is aimed at hunters, wildlife observers, and anyone who spends long periods behind binoculars in the first and last light of the day, when contrast and brightness matter most. Within the range, the B2 focuses on a larger-objective format that balances reach with low-light capability.

The series uses Abbe-Koenig prisms, extra-low-dispersion glass, and an optical field flattener to deliver a bright image with strong contrast and better edge-to-edge consistency. That combination is especially useful when scanning large areas, because detail remains easier to read across more of the viewing field. The B2 line also follows a durable mechanical design, with a magnesium frame, nitrogen-purged internals, and waterproof, fog-proof construction for demanding outdoor use. Maven positions the B2 as a premium full-size hunting binocular for users who want Japanese components, tripod adaptability, and a design that remains composed during long observation sessions.

About the Maven B2 11x45

The Maven B2 11x45 is the higher-magnification version of the B2 concept, built for users who want more reach without moving into the size and weight of a large 50 mm or 56 mm binocular. Its 11.00 x magnification helps pull distant detail closer for judging terrain, locating animals across open country, or following movement at longer ranges, while the 45.00 mm objective preserves useful brightness for early morning and evening glassing.

The optical layout combines Abbe/Koenig roof prisms, fully multicoated lenses, and high light transmission to support a bright, high-contrast image. In practice, that means better separation of fine detail from shadowed backgrounds and less strain during extended observation. The 105.00 m/1000m field of view is controlled rather than extra wide, which suits the binocular’s emphasis on detail recognition at distance, while the 66.00 ° apparent field of view helps maintain an immersive view for a binocular in this magnification class.

For handling, the binocular uses a central focusing system and a right-eyepiece diopter adjustment, allowing quick setup and straightforward fine tuning. The 16.70 mm eye relief gives practical usability for many eyeglass wearers, and the 4.09 mm exit pupil offers a sensible balance between image brightness and compactness. A magnesium housing, waterproof and fogproof sealing, and tripod adaptability make the B2 11x45 well suited to long sessions on exposed ridgelines, in wet weather, or from a fixed glassing position where stability matters most.

About Maven

Maven Outdoor Equipment Company was founded in 2013 in Lander, Wyoming. The company focuses on sport optics including binoculars, spotting scopes, riflescopes, rangefinders, and monoculars, with product families such as the B, C, S, RS, CRS, RF, and CRF series. Maven is a United States optics company that built its reputation around a direct-to-consumer model and a product range that separates premium and mid-range lines clearly by materials and construction.

For binoculars in particular, Maven’s B Series uses Japanese-produced glass and magnesium frames, while the company states that its B and S Series optics use Japanese components and are assembled in a military-standard facility in San Diego. Maven also inspects and tests B and S Series optics at its Lander headquarters. That background is especially relevant to the B2 11x45, which sits in the company’s premium binocular offering and reflects Maven’s emphasis on robust construction, careful quality control, and field-oriented optical design.
