The 10x50 X-Trail Reverse Porro Binocular from Barska has a reverse Porro design with BAK7 glass and multicoated optics; creating a viewing experience of clarity and high contrast. Reverse Porro prisms are positioned so that the objectives are closer to each other than those found in the classic Porro design. This creates a more compact, smaller housing. The ruby tinted lenses help reduce glare. Rubber armoring with indented finger-holds provides a protective non-slip grip as well as added protection for the housing and internal optics. This optic is an all around compact scope for sporting events, nature walks or any situation where a convenient compact binocular could enhance the visual experience.
