Main Features

Nikon PROSTAFF 3S BinocularsForming part of the already well established series of Nikon PROSTAFF binoculars which all contain fully waterproof, roof prism models, the new PROSTAFF 3S binoculars are only currently available with 42mm objective lenses and come with either 8x or 10x magnifications.

The roof prisms are silver mirror coated and they have multi-coated lenses. The body is fully o-ring sealed and are said by the company to be waterproof and tested to a depth of 1m for 10 minutes. The shell is filled with nitrogen gas to ensure that internal lenses do not fog up.

The twist-up eye-cups have multi position stops and both the 10x42 and 8x42 models have a good amount of eye-relief making them a good choice for those who wear glasses.
