Snypex 10x42 Infinio Focus Free Water Proof Roof Prism Binocular with 5.6 Degree Angle of View, 4.2mm Exit Pupil, 18.5mm Eye Relief, Fully Multicoated

The Snypex Infinio Focus Free 10x42 Binocular features a focus-free design that gets you viewing faster without wasting precious time trying to find and manipulate a focus wheel. Anti-reflection fully multicoated optics reduces light loss and maximizes the amount of light that reaches your eyes. Designed for long-term comfortable use, the housing is made of a lightweight and durable fiberglass-reinforced polycarbonate housing with an open-bridge design to further reduce the weight, while providing a large holding surface.

The housing's exterior is covered with a rubber armor that protects the binocular from impacts and provides a secure non-slip grip. Twist-up eyecups allow you to customize the eye relief and can be used with or without eye wear.
