Optimized for comfortable viewing on the water, the Nikon 7x50 Action Extreme ATB Binoculars are an ideal optic for boaters who often find themselves in rough or rolling seas. With an exceptionally wide exit pupil, users will enjoy viewing the entire scene presented before them with horizon line movement greatly minimized, plus its long eye relief provides room to move the eyepieces back for a more comfortable viewing position. These design features help mitigate the disorientation and discomfort often experienced when looking through optical devices in the water. The traditional Porro prism design, when combined with oversized objectives, BAK4 prism glass, and fully multi-coated anti-reflective optics, delivers immersive, high-contrast views that are bright and sharp, with accurate colors and a rich depth of field for so that 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. The Nikon Tether Retractable Rangefinder, in basic black, was developed to help you safely manage the simultaneous use of binoculars and a ranging device. Additionally, a Crooked Horn binocular harness relieves neck strain by redistributing the weight of your binoculars to your shoulders.
