Description

Overview

The new binocular PROSTAFF 7S 10x30 has been fully redesigned to enhance both style and functionality. Enjoy a completely new optical system. It was created exclusively for the PROSTAFF 7S series and succeeds in delivering sharp images of stunning quality. Waterproof and fog-free, it features an improved grip for a better handling in all kinds of weather. The PROSTAFF 7S is made for bird watching and wildlife observation. For that reason, viewing comfort was a key priority. A lot of attention went into details such as the knurling on the focusing ring, which makes adjusting the binocular easy and natural.
