The Nikon 10x50 Central Focus Waterproof Black are an ideal high-power optic for boaters who often find themselves on rough or rolling seas.
To help mitigate the disorientation and discomfort often experienced when looking through binoculars on the water, the Action Extreme has a wide exit pupil and field of view that keeps the entire scene in view and minimises the movement of the horizon line, plus a long eye relief that provides the room to back the eyes off the eyepieces for a more comfortable viewing position. The traditional Porro prism design, when combined with the over-sized objective lenses, BAK4 prism glass, and anti-reflection fully multicoated optics, delivers high-contrast views that are bright and sharp, with accurate colours and a rich depth of field so users can differentiate the relative distance between objects in the view—even in low light.
