INJIE Guiying 10×42 ED High-Power HD Binoculars

I. Product Features

ED Extra-Low Dispersion Lenses:
ED (Extra-Low Dispersion) glass reduces chromatic aberration caused by long focal lengths. Different wavelengths of visible light refract differently, which can prevent them from converging on the same plane, especially in long-range observations, causing color fringing (red and blue). ED lenses focus all wavelengths to the same point, producing sharp, vivid images with strong contrast and true-to-life color reproduction.

BAK4 Multi-Coated Prisms:
BAK4 glass has a higher refractive index than BK7, improving light transmission and clarity. This ensures distortion-free viewing, enhanced contrast, and sharper images, even in low-light conditions.

IPX7 Nitrogen-Filled Waterproof:
Ideal for outdoor activities, rainy conditions, and humid environments. Nitrogen-filled waterproofing withstands submersion up to 1 meter for 30 minutes, making it ready for any weather.

Master Craftsmanship & Modern Design:
Lightweight and highly durable, with anti-slip side grips for stable handling and premium feel. The overall ergonomic design ensures comfortable use during extended observation sessions.

Applications

Outdoor travel, wilderness exploration, sports events, concerts, power line inspection, forestry surveys, security & law enforcement, military patrol, industrial inspection, marine observation, archaeological research, railway route surveying, land and natural resources investigation, and more.
