The B.2 11x45 is the binocular that put Maven on the map with serious Western hunters. Instead of chasing the crowded 10x42 formula, Maven paired an unusual 11x magnification with 45mm objectives and Abbe-Koenig prisms - the same prism architecture Zeiss uses in its brightest hunting glass - and the result earned Binocular of the Year honors from BestBinocularsReviews with an 85% 'Outstanding' score. Hunters on forums consistently describe the view as alpha-adjacent: in side-by-side tests it hangs with $2,000+ European 8x42s for brightness until the very last light, when its 4.1mm exit pupil finally concedes.
The practical experience is defined by that optical ambition. ED glass keeps fringing essentially invisible, contrast and color are vivid without artificial tint, and the all-metal focus wheel is smooth and precisely geared with zero play. The magnesium chassis feels like it costs more than it does, and the top-hinge design leaves plenty of barrel to wrap your hands around - which matters, because at 33.25 ounces and over 7 inches long this is a big, deliberate instrument. The gripes are mostly around the edges: thin, firm eyecup rubber, a non-locking unmarked diopter, external objective covers, and no hard case in the box.
This is the pick for hunters and wildlife watchers who glass long and far - ideally from a tripod, where the 11x resolves detail a 10x42 simply can't. At $1,375 direct from Maven it undercuts the European alphas by roughly half while giving up little in the glass, and the unconditional lifetime warranty (owners report free full-service refurbs, even on second-hand pairs) sweetens the math. Backpackers and birders who prioritize a wide field and low weight should look at the 9x45 sibling or Maven's own B.1.2 10x42 instead; the 11x45 is the one you buy for picking apart distant basins at dawn.
Pros
- +Scored 85% ('Outstanding') and won Binocular of the Year 2018 from BestBinocularsReviews, which called the optical performance 'superb'
- +Abbe-Koenig prisms reflect 100% of internal light - in side-by-side testing the B.2 matched an alpha-grade 8x42 for brightness in daylight and low-light forest conditions
- +ED glass keeps color fringing 'as little as any I have ever seen' per long-term reviewers, with vibrant, natural color and excellent contrast
- +Reviewers repeatedly describe it as 'European-level optical performance at roughly half the price' of Swarovski and Zeiss equivalents
- +Magnesium alloy chassis and an all-metal, precisely geared focus wheel earn build-quality marks of 9/10 - materials and craftsmanship called 'truly superb'
- +11x magnification plus tripod adaptability pulls apart distant hillsides in a way 10x42s can't, which is why Western hunters on forums treat it as a glassing-tripod staple
- +Top-hinge single-bridge design leaves a large open barrel area for a steady, comfortable grip despite the higher magnification
- +Unconditional lifetime warranty with praised turnaround - owners report Maven running full optical tests and re-attaching worn armor and eyecups on used pairs at no charge
Cons
- −Heavy and long for the class - 33.25 oz and 7.1 inches, a direct consequence of the Abbe-Koenig prism design, so it's a poor fit for ounce-counting hikers
- −The 4.1mm exit pupil gives ground to big-exit-pupil alphas in the last minutes of extreme twilight
- −Diopter ring has no lock and no reference markings, so shared or bumped settings are annoying to restore
- −Eyecup rubber is thin and quite hard - comfort during marathon glassing sessions trails plusher competitors
- −Only a soft drawstring bag is included; Maven's fitted hard case is a separate purchase
- −Objective lens covers fit externally and look generic next to the otherwise premium fit and finish
- −314 ft field of view is merely average - noticeably narrower than the sibling 9x45's 377 ft, and some owners end up preferring the 9x for handheld use
- −Direct-to-consumer only, so you can't try before buying, and brand recognition and resale value still lag the European alphas
