Optical Performance
ED (Extra-Low Dispersion) Glass
Premium ED elements significantly reduce chromatic aberration caused by wavelength dispersion. This results in sharper edge definition, higher contrast, and true-to-life color reproduction — especially critical in long-distance observation.
BaK4 Roof Prism System
High-refractive-index BaK4 prisms provide superior light transmission compared to standard BK7 prisms, producing brighter, clearer images with minimal edge distortion.
Fully Multi-Coated (FMC) Optics
All air-to-glass surfaces are treated with fully multi-layer broadband coatings to maximize light transmission across the visible spectrum and ensure natural color balance.
Built for Outdoor Reliability
Nitrogen-Filled & IPX7 Waterproof
The internal nitrogen-filled structure prevents fogging and internal moisture. Rated IPX7 waterproof, the binoculars can withstand immersion in up to 1 meter of water for 30 minutes under controlled conditions.
Durable & Ergonomic Construction
The reinforced composite body combines strength and weight balance for long-term durability. Anti-slip side panels enhance grip stability, while the ergonomic design ensures comfort during extended observation.
