A 10x50 binocular with fully multi-coated optics and BaK-4 roof prisms: the largest objectives in the G400 lineup gather 42% more light than the 42mm models.

The 50mm aperture produces a 5mm exit pupil at 10x magnification. Silver, phase-correction, and high-reflective dielectric coatings on the BaK-4 prisms maintain contrast. Waterproof construction handles any weather. Twist-up eyecups with 17mm eye relief accommodate eyeglass wearers.
