Optimized for comfortable viewing on the water, the Nikon 7x50 Action Extreme ATB Binoculars are an ideal optic for boaters who often find themselves on rough or rolling seas. With an exceptionally wide exit pupil, users will enjoy seeing the entire scene laid out before them with the movement of the horizon line greatly minimized, plus their long eye relief provides room to back off the eyepieces for a more comfortable viewing position. These design features help mitigate the disorientation and discomfort often experienced when looking through optical devices on the water. The traditional Porro prism design, when combined with the over-sized 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. For hunters, birders, and outdoor enthusiasts, the large exit pupil and large objectives make the Action Extreme perfect for scanning and identifying game at dawn and dusk, or under heavy canopies.
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. Their 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. For hands-free use, the binoculars are tripod mountable to eliminate arm fatigue and greatly reduce vibrations. A tethered one-piece ocular rainguard covers the eyecups as they hang around the neck and prevents rain and spraying water from filling them, and the objective 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 7x50 Action Extreme binoculars are engineered to deliver the performance required by discerning observers—especially boaters and outdoor enthusiasts who won't let inclement weather and rough seas keep them at home or in a safe harbor.
