The Nikon 12x50 Action Extreme ATB Binocular is an ideal optic for boaters who often find themselves scanning the water for shoals, shore, and buoys or just trying to identify obstacles on rough or rolling seas. To help mitigate the disorientation and discomfort often experienced when looking through high-power binoculars on the water, the Action Extreme has a wide field of view and a generous exit pupil that keep the entire scene in view and minimize the movement of the horizon line, plus a comfortable 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 oversized objective lenses, BAK4 prism glass, and anti-reflection fully multi-coated optics, delivers immersive high-contrast views that are bright and sharp, with accurate colors and a rich depth of field so users can differentiate the relative distance between objects in the view even in low light.
Complementing this optical performance are design details that allow the Action Extreme to withstand the rigors of outdoor life. The Porro prism design has an inherently balanced and comfortable feel in the hand for long-duration observation sessions, and the chassis is wrapped in a rubber armor that provides a sure and reliable grip in cold and wet weather. Its optical tubes are nitrogen filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature and environmental conditions. Because of the high magnification and large objectives, hand holding the binocular for long periods can cause fatigue and excessive hand shake, so Nikon made it tripod mountable for easy and convenient hands-free use. A tethered one-piece ocular rainguard covers the eye cups as they hang around the neck and prevents rain and spraying water from filling them, and the object lens caps can clip onto the neck strap to keep them safe from blowing overboard or being lost on the forest floor.
From the trail, to the range, to the boat, the 12x50 Action Extreme binocular is engineered to deliver the high-power long-distance performance required by discerning observers—especially boaters and avid outdoor enthusiasts who won't let inclement weather and rough seas keep them at home or in a safe harbor.
