- Field of View at 1000 yards (Maximum Magnification): 152.2 feet (The area of a target at minimum zoom, measured horizontally from the location of viewing, that can be observed.)
- Close Focusing Distance: 10 feet (The closest distance the user can be from an object to obtain a clear, focused view through the lens.)

- Features
- Size: Compact
- Folding Design: true
- Prism Type: Porro (Prisms ensure the proper horizontal and vertical orientation of the view. There are two main types: roof and Porro. Roof prisms, typically more expensive than the alternative, have a more streamlined design due to their glass elements being in line with one another. Porro prisms, though they contribute to a larger form factor, typically provide a wider field of view than roof prisms.)
- Exit Pupil: 5.5 millimeters (The diameter of the beam of light that travels through the lens to the user's eye. Generally, the larger this measurement, the greater the relative brightness and detail of the image.)
- Lens Coating: Fully Coated (Chemical coatings on a lens reduce reflective light loss and improve light transmission. The different coating levels indicate the number of anti-reflective layers and the lens surfaces to which they're applied, ranging from coated (the most basic) to fully multi-coated (typical of high-end optics).)
- Focus System: Center (The most common binocular focusing system is center focus, which features a centered wheel or lever (InstaFocus) between the barrels, and usually additional diopter adjustment. Individual focus binoculars allows each eyepiece to be adjusted independently.)
- Eye Relief: 14 millimeters (The maximum distance between the eyepiece lens and user's eye at which the full field of view can be seen.)
