Maven B3 10x30

• Compact 10x30 format: The 10x magnification gives useful reach for distant wildlife and open-country glassing, while the 30 mm objectives keep the binocular small enough for travel, day hunts, and all-day carry.
• ED glass with Schmidt-Pechan prisms: Extra-low-dispersion glass and quality roof prisms help reduce color fringing and maintain contrast, so fine detail is easier to separate in feathers, antlers, and terrain.
• 94.6% light transmission: Strong transmission for a compact binocular helps preserve image brightness and contrast in shaded woods, overcast conditions, and the first and last light of the day.
• Polymer single-hinge body: The lightweight frame keeps weight down to 467.00 g, making the binocular easier to pack and quicker to bring on target without feeling bulky around the neck.
• Waterproof, fogproof, nitrogen-filled construction: Sealed internals and nitrogen purging help the binocular stay reliable when moving between temperatures or glassing in rain, cold, and damp conditions.

About the Maven B3 Series

The Maven B3 series sits within Maven’s elite B Series optics line and is built for users who want premium binocular performance in a more compact format. The series is aimed at hunters, birders, naturalists, and travelers who need a binocular that is easy to carry but still capable of serious observation. Rather than treating compact size as a compromise, Maven gives the B3 line the same design focus on optical quality and field durability that defines its upper-tier binoculars.

Across the range, the B3 models use Japanese components, extra-low-dispersion glass, Schmidt-Pechan prisms, dielectric reflective coatings, and phase-correction coatings. In practice, that combination is meant to preserve contrast, control chromatic aberration, and keep the image crisp across a wide range of viewing conditions. The series uses a polymer frame to reduce carry weight, and the body is tripod-adaptable for longer observation sessions. Nitrogen purging and IPX7 pressure-tested construction support dependable use in wet weather and changing temperatures. With 6x30, 8x30, and 10x30 configurations, the B3 family covers everything from steady close-range scanning to longer-reach glassing in open country.

About the Maven B3 10x30

The Maven B3 10x30 is the longest-reaching model in the B3 family, built for users who want a compact binocular with enough magnification to pick apart distant detail. Its 10.00 x magnification is well suited to hillside scanning, bird identification at longer distances, and travel or hunting use where a full-size binocular would take up too much space. Paired with a 30.00 mm objective lens, it stays notably smaller and lighter than many 42 mm binoculars, which matters when the binocular is carried all day rather than used only from a fixed position.

Optically, the B3 10x30 balances reach with a useful level of brightness for its class. The 3.00 mm exit pupil, 94.6 % light transmission, and fully multicoated lenses help maintain a clear, contrast-rich image in normal daylight and in subdued conditions where compact binoculars are often pushed hard. Its 113.75 m/1000m field of view is controlled enough for precise observation without making the image feel overly narrow for scanning. The 15.30 mm eye relief gives a practical viewing position for many users, including those who wear glasses.

The handling also fits the binocular’s intended role. A 467.00 g body, central focusing system, and single-hinge design make it quick to deploy and easy to steady. The right-eye diopter adjustment allows the image to be tuned to the user’s vision, while the waterproof, fogproof, nitrogen-filled housing supports reliable use in rain, cold mornings, and changing elevations. For users who prioritize packability but still need true 10x observation, this model is the most distance-oriented option in the B3 line.

About Maven

Maven Outdoor Equipment Company was founded in 2013 and is based in Lander, Wyoming. The company focuses on sport optics including binoculars, spotting scopes, riflescopes, rangefinders, and monoculars, and it is known for selling directly to consumers rather than through a traditional retail network. That business model has become a defining part of Maven’s identity in the optics market.

Within its lineup, Maven’s B and S Series products are positioned as its more premium optics, and the company inspects and tests those lines for quality assurance at its Lander headquarters. Maven’s catalog spans multiple families, including the B, C, S, CS, RS, CRS, RF, and CRF series, covering hunting optics, observation optics, and shooting applications. For binoculars such as the B3 series, Maven combines Japanese-produced components with assembly in the United States, reflecting the brand’s emphasis on optical performance, practical field design, and consistent quality control.
