4. Product Overview
Figure 1: Bushnell Falcon 13-3450 10x50 Binoculars. This image shows the overall design of the binoculars, including the objective lenses, eyepieces, and the central focusing mechanism.
The Bushnell Falcon 13-3450 binoculars feature a robust design with a dark earth finish. Key components include the objective lenses (50mm), eyepieces, and the unique Instant Focus lever for rapid adjustments. The binoculars are equipped with Porro prisms (BaK-7 type) for a clear and bright image. An eye relief of 9mm is provided, and the exit pupil is 5mm.
5. Setup
5.1. Attaching the Neck Strap
- Thread the ends of the provided neck strap through the strap lugs on each side of the binocular body.
- Secure the strap by feeding it back through the buckle, ensuring it is tightly fastened to prevent accidental drops.
5.2. Adjusting Eyecups
The eyecups can be adjusted to optimize viewing comfort and field of view, especially for eyeglass wearers.
- For non-eyeglass wearers: Use the eyecups in the fully extended position.
- For eyeglass wearers: Fold down or retract the eyecups to bring your eyes closer to the ocular lenses, allowing for a full field of view.
5.3. Adjusting Interpupillary Distance (IPD)
The interpupillary distance is the distance between the centers of your pupils. Adjusting this ensures a single, circular field of view.
- Hold the binoculars up to your eyes.
- Grasp each barrel firmly and move them closer together or further apart until you see a single, clear circular image.
6. Operating
6.1. Focusing with Instant Focus
The Bushnell Falcon 13-3450 features an "Instant Focus" lever for quick and precise focusing.
- Point the binoculars at an object you wish to view.
- Locate the "Instant Focus" lever, typically positioned near the center hinge.
- Move the lever back and forth until the image appears sharp and clear. This system allows for rapid adjustments across different distances.
7. Maintenance
7.1. Cleaning Lenses
Proper lens cleaning is crucial to maintain optical clarity.
- Gently brush away any dust or large particles from the lens surface using a soft lens brush or compressed air.
- Apply a small amount of lens cleaning fluid (specifically designed for optics) to a clean microfiber lens cloth.
- Wipe the lens surface in a circular motion, starting from the center and moving outwards.
- Avoid using abrasive cloths, paper towels, or household cleaners, as these can scratch or damage lens coatings.
7.2. Storage
When not in use, store your binoculars in their protective carrying case in a cool, dry environment. Avoid extreme temperatures and high humidity.
