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. Because of the high magnification and large objectives, hand holding the binoculars for long periods can cause fatigue and excessive hand shake, so Nikon made the tripod mountable for easy and convenient hands-free use. 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 10×50 Action Extreme binoculars are engineered to deliver the high-power long-distance performance required by discerning observers—especially boaters and avid outdoor enthusiasts who don’t let inclement weather and rough seas keep them at home or in a safe harbor.
