Ideal for boaters who often find themselves on rough or rolling seas or outdoor enthusiasts who won't let bad weather keep them inside, the Nikon 8x40 Action Extreme ATB Binoculars?are an invaluable addition to any kit.





Their moderate-sized objective lenses deliver enhanced low-light performance versus smaller models, without the associated bulk or additional weight of larger ones, enabling them to be worn around the neck or carried without causing fatigue. To help mitigate the disorientation and discomfort often experienced when looking through binoculars on the water, the Action Extreme have a wide field of view and a comfortable exit pupils that keep the entire scene in view and minimize 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, BAK4 prism glass, and anti-reflection fully multi-coated optics deliver immersive high-contrast views that are bright and sharp, with accurate colors and a rich depth of field.





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. 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 8x40 Action Extreme binoculars are engineered to deliver the performance required by discerning observers without the bulk and weight of larger models.
