General
- Product Name: Granite 12 x 50 Waterproof Binoculars
- Brand: Celestron
- Model Number: 71376
- Color: Black
Imaging
- Magnification: 12 times
- Objective Lens Diameter: 50 millimeters (Generally, the larger the diameter of the objective lens, the greater the light-collecting power and the brighter images will appear.)
- Field of View at 1000 yards: 279 feet (The area of a target, measured horizontally from the location of viewing, that can be observed.)
- Field of View at 1000 yards (Maximum Magnification): 278.2 feet (The area of a target at minimum zoom, measured horizontally from the location of viewing, that can be observed.)
- Close Focusing Distance: 11.5 feet (The closest distance the user can be from an object to obtain a clear, focused view through the lens.)
- Angular Field Of View (Apparent/degree): 63.8 degrees (Measurement of the angle of the magnified field seen through the lens. The greater the number, the wider the field of view that can be seen.)
- Angular Field Of View (Real/degree): 5.3 degrees (Measurement of the angle of the visible field seen through the lens (without magnification). The greater the number, the wider the area that can be viewed.)
- Angle of View (Maximum Magnification): 5.3 degrees (Measurement of the angle of view that can be seen via the device at its highest magnification.)
Features
- Size: Full Size
- Prism Type: Roof (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.)
- Tripod Mountable: Yes
- Eyecup Type: Twist-up (In addition to blocking peripheral light, adjustable eyecups can limit or expand the field of view as well as promote comfort for the user.)
- Exit Pupil: 4.2 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: Multilayer 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: 15 millimeters (The maximum distance between the eyepiece lens and user's eye at which the full field of view can be seen.)
Performance

Waterproof/fog-proof design: With rugged rubber-covered magnesium alloy construction enables use in most weather conditions. Open frame/hinge style, thumb indentations and finger ridges provide a firm grip and comfortable handling.
12x magnification and 50mm-diameter extralow-dispersion (ED) glass lenses: Reduce chromatic aberration, field curvature and distortion and optimize edge-to-edge sharpness and color correction to bring your subject close with stunning clarity.
279' at 1000 yards field of view: Lets you examine a large area.
Focus knob and diopter ring: For precision viewing.
High-reflectivity dielectric- and phase-coated optics: Along with BaK-4 prisms allow optimum light transmission and correct for phase shift to enhance object brightness and produce excellent image clarity and contrast.
Twist-up eyecups: Allow comfortable use when wearing glasses.
Tripod-adaptable design: Lets you connect a tripod (not included) to enhance binocular stability, resulting in improved image quality while you observe objects.
Harness and wide binocular straps: Allow for comfortable wearing during extended viewing sessions. Soft carrying case makes the binoculars easy to take with you on the go.
