Bushnell Prime 10x42

• 10x42 configuration: The 10x magnification gives useful reach for scanning open ground, wildlife observation, and general field use, while the 42 mm objective size keeps the binocular compact enough for all-day carry.
• Roof prism design: The Schmidt/Pechan roof prism layout keeps the Bushnell Prime 10x42 slim and easy to pack, making it a practical choice for hiking, hunting optics, and bird watching where bulk matters.
• 19 mm eye relief: Generous eye relief helps maintain a full image with a relaxed viewing position and makes this model more comfortable for eyeglass wearers during longer sessions behind the glass.
• IPX7 waterproof and nitrogen filled: The sealed, fogproof construction helps the binocular stay usable in rain, damp mornings, and changing temperatures, reducing the risk of internal fogging in the field.
• Fully multi-coated optics: Multi-coated lenses support better light transmission and improved contrast, which helps with detail recognition in low, flat light and during the first and last part of the day.

About the Bushnell Prime Series

Bushnell Prime binoculars sit in the brand’s accessible, field-oriented range and were documented in Bushnell’s 2019 catalog as a roof prism series covering practical everyday formats from compact models up to full-size configurations. The series is built around features that matter in real outdoor use rather than unnecessary complexity, making it well suited to hunting, birding, and general nature observation.

A defining part of the series is its combination of fully multi-coated lenses and Bushnell’s EXO Barrier on the exterior lens surfaces. In practice, that means better resistance to water, oil, dust, and debris on the glass, along with the contrast and brightness needed for regular field use. Bushnell also specifies IPX7 water resistance and dry-nitrogen fog protection for Prime binoculars, so the series is designed to cope with wet weather and rapid temperature changes. Across the range, the use of roof prisms keeps the binoculars streamlined and easy to carry, while the available model spread from 10x25 to 12x50 gives users a choice between portability, wider viewing comfort, and longer-distance observation.

About the Bushnell Prime 10x42

The Bushnell Prime 10x42 is the balanced, all-round model in the series, combining 10x magnification with a 42 mm objective lens for a format that works well across mixed terrain. It offers enough reach for identifying game, following birds at distance, or checking detail across open country, while remaining compact enough for regular carry on a strap or in a pack. With a 102 m/1000m field of view, it stays practical for scanning and tracking movement without feeling overly narrow.

The optical layout uses a Schmidt/Pechan roof prism design in a single-hinge body, which keeps the binocular trim in the hand and easier to pack than bulkier prism systems. A 4.20 mm exit pupil helps maintain a bright, easy-to-acquire image in typical daylight and fading evening conditions, while the 19.00 mm eye relief improves comfort during extended observation and gives eyeglass wearers more flexibility in achieving a full sight picture. The central focusing system supports quick adjustment from near to far subjects, and the right-eyepiece diopter allows the binocular to be tuned to the user’s eyesight for a sharper, more relaxed view.

For field durability, the housing is IPX-7 waterproof, nitrogen filled, and fogproof, so it is better prepared for rain, damp hides, cold mornings, and changing temperatures. The tripod-adaptable design also adds stability for longer glassing sessions, which is useful when observing distant wildlife or reducing fatigue over time.

About Bushnell

Bushnell was founded in 1948 by Dave Bushnell, who began selling optical products from a photographic shop in Pasadena, California. The company developed into a specialist in sports optics and outdoor products, with product categories that include binoculars, riflescopes, red dot sights, rangefinders, spotting scopes, and trail cameras. Bushnell’s catalog is aimed at practical field use across hunting, target shooting, birding, and nature observation.

Within its lineup, Bushnell has built recognizable families such as Legend, Prime, Elite Tactical, and AR Optics, each serving different users and applications. One of the brand’s notable optical technologies is EXO Barrier, a lens coating developed to repel water, oil, dust, and debris on exterior glass surfaces. Bushnell became part of a larger outdoor-products group when ATK acquired Bushnell Group Holdings on November 1, 2013, but the brand has remained closely associated with accessible, field-focused optics.
