Familiarize yourself with the key components of your Bushnell Legend 10x50 Binoculars:

- Objective Lenses: The large lenses at the front of the binoculars that gather light.
- Eyecups: Adjustable cups around the eyepieces for comfortable viewing, especially for eyeglass wearers.
- Diopter Adjustment Ring: Located on the right eyepiece, used to compensate for differences in vision between your eyes.
- Center Focus Wheel: The large wheel located between the barrels, used for focusing both barrels simultaneously.
- Strap Lugs: Attachment points for the neck strap.
- Tripod Adapter Thread: A threaded socket (usually under a cap) for mounting the binoculars on a tripod (adapter sold separately).
Initial Setup
1. Attaching the Neck Strap
Thread the ends of the neck strap through the strap lugs on each side of the binocular body. Ensure the strap is securely fastened before use to prevent accidental drops.
2. Adjusting the Eyecups
Your Bushnell Legend binoculars feature twist-up eyecups for comfortable viewing with or without eyeglasses.
- For Non-Eyeglass Wearers: Twist the eyecups counter-clockwise until they are fully extended (up position). This positions your eyes at the optimal distance from the eyepieces.
- For Eyeglass Wearers: Twist the eyecups clockwise until they are fully retracted (down position). This allows you to see the full field of view while wearing your glasses.

3. Adjusting Interpupillary Distance (IPD)
The interpupillary distance is the distance between the centers of your pupils. To match this to your binoculars:
- Hold the binoculars up to your eyes and look through them.
- Grasp each barrel firmly and move them closer together or further apart until you see a single, clear circular field of view.
4. Focusing Your Binoculars
To achieve a sharp image, you need to adjust both the center focus wheel and the diopter setting.
- Set the Diopter: Close your right eye or cover the right objective lens. Look through the left eyepiece with your left eye and rotate the center focus wheel until the image is sharp.
- Adjust the Diopter Ring: Close your left eye or cover the left objective lens. Look through the right eyepiece with your right eye and rotate the diopter adjustment ring (on the right eyepiece) until the image is sharp. Do not use the center focus wheel for this step.
- Final Focus: With both eyes open, use the center focus wheel to focus on objects at varying distances. The diopter setting should now be correct for your eyes and will not need to be adjusted again unless a different user uses the binoculars.

Operation
Once your binoculars are set up, they are ready for use. Simply point them at your desired subject and use the center focus wheel to achieve a clear image.

Care and Maintenance
Cleaning Lenses
Proper cleaning of the lenses is crucial for maintaining optical quality. Always use the provided lens cleaning cloth or a soft, lint-free cloth designed for optics.
- Gently brush away any dust or large debris from the lens surface.
- Apply a small amount of lens cleaning fluid (if necessary, and specifically designed for optics) to the cloth, not directly to the lens.
- Wipe the lens surface in a circular motion, starting from the center and moving outwards.
- Avoid excessive rubbing or using abrasive materials, which can scratch the lens coatings.
Storage
When not in use, store your binoculars in their protective carrying case in a cool, dry place. Avoid exposing them to extreme temperatures or high humidity for extended periods.
Waterproof Features
The Bushnell Legend 10x50 Binoculars feature IPX7 waterproof construction, meaning they can withstand submersion in 1 meter of water for 30 minutes. They also include Rainguard lens protection. While designed for rugged use, it is recommended to dry the binoculars thoroughly after exposure to water to prevent water spots and maintain their condition.

Troubleshooting
If you encounter issues with your binoculars, refer to the following common problems and solutions:
- Image is blurry or out of focus:
Ensure you have correctly adjusted the interpupillary distance, the center focus wheel, and the diopter adjustment ring. Refer to the "Focusing Your Binoculars" section for detailed steps. - Dark edges or vignetting in the field of view:
This often indicates incorrect interpupillary distance. Adjust the barrels until you see a single, clear circular image. Also, ensure your eyecups are set correctly for your viewing preference (up for non-eyeglass wearers, down for eyeglass wearers). - Double image:
This is typically caused by incorrect interpupillary distance. Adjust the distance between the barrels until the two images merge into one. - Difficulty seeing clearly with eyeglasses:
Make sure the eyecups are fully retracted (down position) when wearing eyeglasses. - Fogging of lenses:
While the binoculars are waterproof and nitrogen-purged to prevent internal fogging, external fogging can occur in humid conditions or rapid temperature changes. Allow the binoculars to acclimate to the ambient temperature, or gently wipe the exterior lenses with a clean, dry cloth.
