Product Description

These 12x50 binoculars let you experience the variety of glasses that nature has to offer with its excellent optical performance and unparalleled wide-angle field of view.

The wide viewing angle helps you find what you need faster.


Filled with nitrogen to minimize the effects of temperature changes, these 12x50 binoculars are ideal for marine applications.
