4. Setup and Adjustments
4.1. Interpupillary Distance Adjustment
Hold the binoculars with both hands and look through them. Adjust the distance between the two barrels by moving them closer together or further apart until you see a single, clear circular field of view. This ensures proper alignment with your eyes.
4.2. Focusing
- Center Focus Wheel: While looking through the binoculars, rotate the large center focus wheel until the image in the left eyepiece is sharp and clear.
- Diopter Adjustment: Close your left eye and use the diopter ring on the right eyepiece to focus the image in your right eye. Once adjusted, both eyepieces should be in focus for your individual vision.
4.3. Zoom Adjustment
The binoculars feature a convenient thumb-lever for adjusting the magnification. Move the lever to smoothly transition between 8x and 24x zoom. Remember to re-focus after changing the magnification.
4.4. Eyecup Adjustment
The eyecups can be folded down for users wearing eyeglasses, allowing them to view the full field of view comfortably. For users not wearing eyeglasses, keep the eyecups extended.
5. Operating Tips
5.1. Long-Range Viewing
For stable viewing at higher magnifications (e.g., 24x), especially during extended observation periods, it is recommended to mount the binoculars on a tripod using the integrated tripod adaptor. This minimizes hand shake and provides a clearer, more comfortable image.

5.2. Low-Light Conditions
The large 50mm objective lenses are designed to gather significant light, making these binoculars effective for viewing in dim conditions, such as dawn, dusk, or for stargazing. The ruby lenses also help manage glare from bright light sources like the moon.

6. Maintenance and Care
6.1. Cleaning Lenses
Use the provided lens cleaning cloth or a soft, lint-free cloth to gently wipe the lenses. For stubborn smudges, a small amount of lens cleaning fluid designed for optics can be applied to the cloth, not directly to the lens. Avoid using abrasive materials or excessive force, as this can scratch the lens coatings.
6.2. Storage
When not in use, store the binoculars in their carrying case with the lens covers attached. Keep them in a cool, dry place away from direct sunlight and extreme temperatures to prevent damage to the optics and rubber armor.
6.3. Water and Dust Resistance
These binoculars are designed with rubber armor for enhanced durability and some resistance to light moisture and dust. However, they are not fully waterproof and should not be submerged in water. Always wipe off any moisture immediately after exposure.
7. Troubleshooting
- Blurry Image: Ensure both the center focus wheel and the right eyepiece diopter are correctly adjusted for your vision. Check that the interpupillary distance is set correctly.
- Double Image: This usually indicates incorrect interpupillary distance. Adjust the distance between the barrels until a single, unified image is achieved. If the problem persists, the binoculars may require professional collimation.
- Difficulty Zooming: Ensure the zoom thumb-lever moves freely. If stiff, check for any obstructions. Do not force the mechanism.
