Introductions of 10x42 Binoculars
|
* Fully Multi-Coated (FMC) optics and premium BaK-4 prisms enable superior resolution, avoid chromatic aberration, and guarantee excellent color fidelity, clarity and light transmission. |
Comparative Advantages
1. High refractive index BAK4 prism prevents light loss through optics and provides unmistakable brightness. Meanwhile, FMC green film optical glass lenses with high light transmission coatings create stunning images and protect your eyes.
2. These binoculars are powerful and easy to use, with a single turn of the large central focus knob for sharp image quality.
3. Adjustable twist eye mask for comfortable use. Enjoy a comfortable viewing experience even with your glasses on. Simply rotate the eyecup up or down to see the entire field of view. The central focus wheel requires minimal rotation for fast, near-infinite absolute sharpness.
4. Powerful magnification and wide field of view. Designed for outdoor activities such as climbing, hiking, driving, wildlife and landscape watching. This power can also be used to watch big dramas, concerts, football matches, and more.
5. Lightweight binoculars are great for travel and hunting. A durable body with non-slip rubber armor provides a solid grip for a great user experience.
