Delta Optical Chase 8x42 ED

• ED objective lenses: ED glass helps suppress color fringing on high-contrast edges, so fine detail in plumage, antlers or distant terrain stays cleaner and easier to read in daylight observation.
• 8x42 configuration: The combination of 8x magnification and a 42 mm objective gives a steady handheld view with a generous 5.25 mm exit pupil, making the binocular practical for long sessions in the field.
• Wide field of view: A 135.45 m/1000m field of view makes it easier to follow moving birds, scan woodland edges and maintain orientation when observing larger scenes.
• Roof-prism, central-focus design: The Schmidt/Pechan roof prism layout keeps the binocular slim and easy to carry, while central focusing allows quick adjustment when subjects change distance.
• Waterproof, nitrogen-filled housing: Waterproof construction, fogproof performance and nitrogen filling help the binocular stay usable in rain, damp air and changing temperatures.

About the Delta Optical Chase Series

The Delta Optical Chase series is a family of ED roof-prism binoculars built for users who want a versatile field optic for nature observation, tourism and daytime hunting. The range includes 8x42, 10x42, 10x50 and 12x50 models, giving the series a clear spread from general-purpose handheld use to higher-magnification observation from more stable positions. Across the line, Delta Optical uses ED glass in the objective system to reduce chromatic aberration, which helps preserve cleaner edges and more natural contrast when viewing branches against bright sky, birds in flight or game at longer distances.

Every Chase model uses a roof-prism design with central focusing, keeping the binoculars compact in the hand and straightforward to operate in the field. The series also features a waterproof IPX7 construction, which suits outdoor use where rain, wet vegetation and rapid weather changes are part of normal conditions. Within Delta Optical's binocular range, the Chase line sits as a practical step toward improved optical correction and field durability while maintaining the handling qualities expected from modern all-round hunting optics and bird watching binoculars.

About the Delta Optical Chase 8x42 ED

The Delta Optical Chase 8x42 ED is the most universal configuration in the series, combining 8x magnification with a 42 mm objective lens for balanced handheld use across woodland, open country and general wildlife observation. This format gives enough reach to identify detail at distance without the narrower view and increased shake that often come with higher magnification. Its 135.45 m/1000m field of view supports fast scanning and helps when tracking moving subjects, while the 2.00 m close focus also makes it useful for nearby observation.

ED objective lenses and fully multicoated optics are central to the model's character. In practice, they help maintain better contrast and reduce distracting color fringing, which matters when observing dark subjects against bright backgrounds or reading fine detail in feathers and fur. The Schmidt/Pechan roof-prism system keeps the body trim, and the single-hinge construction makes the binocular easy to pack and comfortable to carry on a neck strap for extended walks.

Central focusing allows quick, intuitive adjustment, and the 16.00 mm eye relief offers a more comfortable viewing position, especially during longer sessions. With waterproof and fogproof construction plus nitrogen filling, the Chase 8x42 ED is built for regular outdoor use where damp mornings, rain showers and temperature changes are common. At 730.00 g, it remains substantial enough to feel secure in the hand without becoming overly burdensome for day-long field carry.

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 involvement in field and sporting optics helps explain the practical design focus seen across its product lines.

Within shooting and observation equipment, Delta Optical is known for product families such as Titanium, Stryker and Hornet. The company states that its sporting scopes use proprietary reticles and anti-reflective coatings, while its Titanium hunting scopes are specified with light transmission above 92%. This background in both observation optics and sporting optics gives the brand a solid reputation among users looking for functional, field-oriented designs rather than purely decorative features.
