Delta Optical Chase 10x42 ED

• ED objective lenses: Extra-low dispersion glass helps control color fringing, so fine detail stays cleaner against bright backgrounds such as sky, water, or sunlit terrain.
• 10x42 configuration: The combination of 10x magnification and a 42 mm objective gives useful reach for wildlife observation and daytime hunting while remaining manageable for all-day carry.
• Roof-prism design: The Schmidt/Pechan prism system keeps the binocular slim and easy to pack, with a shape that sits naturally in the hands during longer glassing sessions.
• Waterproof, nitrogen-filled housing: A sealed body with nitrogen filling resists internal fogging and supports reliable use when moving between cold and warm conditions or working in wet weather.
• Close focus and generous eye relief: A 2.00 m close focus distance and 17.00 mm eye relief make the binocular more versatile at short range and more comfortable for eyeglass wearers.

About the Delta Optical Chase Series

Delta Optical Chase is a family of ED roof-prism binoculars built for users who want a practical field format for nature observation, tourism, and daytime hunting. The series includes 8x42, 10x42, 10x50 and 12x50 models, giving the range enough breadth to cover wider-view general observation as well as higher-magnification use from more open ground. Across the line, Delta Optical uses a roof-prism layout with central focusing, which keeps the binoculars compact, straightforward to operate, and easy to carry over longer distances.

A defining feature of the series is the use of ED glass in the objective lenses. In practice, that helps reduce chromatic aberration, which improves edge definition on branches, feathers, antlers, and other high-contrast details. The Chase series also uses a waterproof construction rated IPX7, making it suitable for field use in rain, damp woodland, and changing temperatures. Within Delta Optical’s binocular range, Chase models sit as versatile all-rounders that balance portability, modern optical design, and the kind of durability expected from hunting binoculars and bird watching binoculars used regularly outdoors.

About the Delta Optical Chase 10x42 ED

Delta Optical Chase 10x42 ED is the most classic all-round format in the series, pairing 10x magnification with a 42 mm objective for a balance of reach, brightness, and portability. That makes it well suited to mixed use: scanning woodland edges, following birds across open ground, or carrying one binocular for travel, hiking, and general wildlife observation. The 112.35 m/1000m field of view is wide enough to keep moving subjects easier to acquire, while the 10x image scale still gives a clear advantage when judging distant detail.

The optical system uses ED glass and fully multicoated lenses, a combination that helps preserve contrast and reduce distracting color fringing in difficult light. The 4.20 mm exit pupil supports a bright, easy view in normal daylight and into the later part of the day, while 17.00 mm eye relief improves comfort for users who observe with glasses. A close focus of 2.00 m also broadens the binocular’s usefulness for nearby subjects such as insects, plants, or birds at short range.

Mechanically, the binocular uses a single-hinge body with central focusing and a central diopter adjustment, keeping operation simple and familiar in the field. The roof - Schmidt/Pechan prism design contributes to a slimmer shape than a comparable Porro binocular, which helps with packability and one-handed handling between observations. With a waterproof, fogproof, nitrogen-filled construction and a stated weight of 730.00 g, this model is built for regular outdoor use without becoming cumbersome on longer walks.

About Delta Optical

Delta Optical traces its beginnings to 1989, when it opened an optics shop for enthusiasts. The company is a Polish manufacturer headquartered in Nowe Osiny, near Mińsk Mazowiecki, and it serves users of optical equipment across astronomy, biology, hunting, and shooting. That broad background helps explain why its catalog covers both observation optics and aiming optics, with product lines developed for different field requirements rather than a single niche.

In sporting optics, Delta Optical states that its scopes use proprietary reticles and anti-reflective coatings, showing a long-standing focus on practical optical performance. Its riflescope range includes the Titanium, Stryker, and Hornet series, while its binocular lineup addresses everyday observation as well as more specialized outdoor use. For products such as the Chase binoculars, the company’s reputation rests on combining functional mechanical design with optical features that matter in real use, including compact roof-prism construction, weather resistance, and glass choices aimed at improving image clarity.
