Our ED glass binoculars, combined with a BAK4 roof prism that's phase coated with a dielectric application process, provide unparalleled clarity and low-light performance. Housed in a magnesium body, they're some of the lightest and toughest binoculars you're ever going to own.

The optical components are made using the highest quality Extra-Low Dispersion (ED) Japanese glass, which are ground down and polished with state-of-the-art equipment. The optical system uses a set of finely lenses, and when combined with the Prime ED glass provides an unmatched clarity of image, depth of field, and field of view. Every lens is meticulously inspected by our production engineers before it goes into one of our binoculars.

Finally, the entire system is inspected once-again, then assembled by hand in a Certified Clean Environment. The final step of the assembly is dry-Argon purging and sealing, ensuring that the entire optical system is shockproof, fogproof, and IP67-rated dustproof and waterproof.
