Alpen Optics Black Tusk 10x42 ED

• 10x42 ED optical format: The 10x magnification gives useful reach for wildlife observation and general field use, while the 42 mm objective size keeps the binocular bright enough for dawn, dusk, and woodland conditions without becoming bulky.
• ED glass with fully multicoated lenses: This optical combination helps reduce color fringing and improves contrast, so fine detail is easier to separate when judging antlers, plumage, or distant terrain.
• Roof prism Schmidt/Pechan design: The compact roof-prism layout keeps the Black Tusk easy to carry on long walks or hunts, while still delivering the straight-barrel handling many users prefer.
• Nitrogen-filled waterproof and fogproof housing: Sealing and internal nitrogen filling help the binocular stay dependable when moving between temperature changes or using it in wet weather.
• Close focus to 2.50 m: A short close-focus distance makes the binocular more versatile, letting it move from scanning distant subjects to observing nearby birds, insects, or detail in vegetation.

About the Black Tusk Series

The Alpen Optics Black Tusk series is built around the idea of a practical field binocular that balances ED glass, weather-resistant construction, and everyday portability. In Alpen Optics’ binocular range, it sits in the part of the lineup aimed at users who want a more refined image than entry-level optics typically provide, but still in a format suited to regular outdoor use. That makes the series relevant for hunting binoculars, bird watching, and general nature observation where clear detail and reliable handling matter more than oversized dimensions.

Typical Black Tusk models use a compact roof-prism layout, fully multicoated optics, and sealed housings intended for changing weather and varied terrain. The series focuses on the core qualities most users notice in the field: good contrast, controlled glare, manageable weight, and a shape that carries comfortably on a strap or harness. Rather than specializing in one narrow role, the Black Tusk family is designed as a versatile all-round option for people who need one binocular to cover scanning open ground, following moving wildlife, and observing detail at medium to long distances.

About the Alpen Optics Black Tusk 10x42 ED

The Alpen Optics Black Tusk 10x42 ED is the classic all-purpose configuration in the series. Its 10x magnification gives enough reach to identify distant animals, pick out detail across fields, or study birds on the far side of a wetland, while the 42 mm objective lenses keep the binocular bright enough for the low-angle light that often defines the most active hours outdoors. This balance is why 10x42 remains one of the most useful formats for both hunting optics and bird watching binoculars.

The optical system combines ED glass with fully multicoated lenses, a pairing that helps preserve contrast and reduce distracting color fringing around high-contrast edges. In practice, that means a cleaner view when looking into branches, reading terrain contours, or separating an animal from a dark background. The 113.00 m/1000m field of view is wide enough to keep moving subjects easier to track than with more specialized high-magnification binoculars, while the 4.20 mm exit pupil supports comfortable viewing in mixed light.

Mechanically, the binocular uses a Schmidt/Pechan roof prism design with central focusing, giving it a slim profile and straightforward one-wheel operation in the field. The right-eyepiece diopter adjustment allows compensation for differences between the user’s eyes, helping the image stay sharp once set. A nitrogen-filled, waterproof and fogproof body adds practical durability for rain, cold mornings, and repeated temperature changes, and the tripod-adaptable design is useful for longer glassing sessions where a steadier image reduces eye fatigue.

About Alpen Optics

Alpen Optics was founded by Tim Gardner in December 1996, and the company introduced its first products in 1997. Its history identifies Rancho Cucamonga, California, as the company’s headquarters. Alpen Optics focuses on field-ready sporting optics, including binoculars, spotting scopes, riflescopes, and thermal optics, which places it squarely in the outdoor observation and hunting categories.

A later step in the company’s development came in 2018, when Explore Scientific acquired Alpen Optics’ trademarks and designs. Across its binocular range, Alpen Optics has developed several distinct product families, including Apex XP, Teton, and Rainier. Those lines show the brand’s emphasis on practical optical improvements such as ED glass, prism systems, and lens coatings chosen to improve contrast, brightness, and color fidelity for real field use rather than display-case specifications alone.
