Product Description

FEIRSH T18 10x50 HD Porro Binoculars – The Outdoor Classic

Experience the world with clarity and depth. The FEIRSH 10x50 Porro Binoculars are designed for outdoor enthusiasts who refuse to compromise on brightness and stability. Whether you are hunting, bird watching, or stargazing, this classic optical powerhouse delivers.

Why Choose Porro Prisms? Unlike roof prism binoculars, the Porro prism design naturally provides a wider field of view and better depth perception, giving you a more immersive "3D" visual experience.

Key Features:

1. Superior Low-Light Performance With a massive 50mm objective lens and a 5mm exit pupil diameter, these binoculars gather significantly more light than 25mm or 42mm models. This makes them exceptional for Low Light Night Vision use, such as at dawn, dusk, or in dense forests (Note: Requires some ambient light).

2. Crystal Clear Optics

• BAK4 Prism: Eliminates the dark edges found in cheaper binoculars, ensuring a round, full, and bright image.

• 18mm Large Eyepiece: Provides comfortable eye relief, reducing eye fatigue during long observation sessions.

3. Rugged & Ergonomic

• Non-Slip Grip: The body is wrapped in durable rubber armor for a secure grip and shock resistance.

• Easy Focus: Features a large central focus wheel for quick adjustments and a right-eye diopter ring to balance vision differences.

User Guide

Step 1: Interpupillary Distance Adjustment (IPD) Hold the binoculars with both hands and fold the barrels inward or outward until the two circular views merge into one single circle. This matches the distance between your eyes.

Step 2: Focusing

1. Close your right eye and sight an object with your left eye. Rotate the Center Focus Wheel until the image is sharp and clear.

2. Open your right eye and close your left eye. Rotate the Right Eyepiece Diopter Ring until the image is sharp.

3. Now that both eyes are in focus, use only the Center Focus Wheel to view different objects.

Maintenance & Care

1. Storage: Keep the binoculars in a ventilated, dry, and clean place to prevent mold. Using desiccant packs in the storage bag is recommended.

2. Cleaning Lenses:

   • Blow away dust first.

   • Use the provided professional cleaning cloth to gently wipe lenses.

   • For stubborn spots (like fingerprints), use a cotton swab with a small amount of alcohol and wipe from the center of the lens outward in a circular motion.

3. Handling: Binoculars are precision instruments. Avoid dropping, heavy pressure, or violent shaking.

4. Waterproofing: While the product is life-waterproof, avoid using it in extreme weather conditions (heavy rain) or submerging it in water unless specified.

5. Safety Warning: NEVER look directly at the sun with binoculars, as this will cause permanent eye damage.
