Nikon 10x50 Action Extreme ATB Binoculars

Nikon 10x50 Action Extreme ATB Binoculars
The Nikon 10x50 Action Extreme ATB Binoculars are an ideal high-power optic for boaters who often find themselves on rough or rolling seas. To help mitigate the disorientation and discomfort often experienced when looking through binoculars on the water, the Action Extreme has a wide exit pupil and field of view that keeps the entire scene in view and minimizes 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, when combined with the over-sized objective lenses, BAK4 prism glass, and anti-reflection fully multicoated optics, delivers 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. 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 handshake, 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 10x50 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.

Optical Performance

• Powerful 10x magnification allows detailed observations of distant subjects on land and sea
• Large 50mm objective lenses provide improved low-light performance versus smaller-objective models, ensuring images are bright even in challenging conditions
• Traditional Porro prism design makes it comfortable to hold and presents a rich depth of field
• High-index BAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortion
• Anti-reflection fully multicoated optics produce neutral and accurate color fidelity and improve contrast and image brightness
• Wide 60° apparent angle of view to minimize the appearance of visible handshake and the disorientation often felt when using high-power optics on rough or rolling seas
• 341-foot field of view at 1000 yards

Use and Handling

• Large slip-resistant center fast-focusing knob is easy to manipulate in cold or wet weather or while wearing gloves
• Right-eye dioptric correction enables users to compensate for individual optical prescriptions for clearer views; large adjustment lever is easy to find and use
• 56-72mm interpupillary adjustment range allows use by a wide variety of people
• Twist-up/click-stop rubber eyecups for comfortable use with or without eyewear
• Tripod mountable with optional adapter that enables hands-free use to eliminate handshake / vibrations and arm fatigue
• Long 17.2mm eye relief helps to reduce eyestrain and improves viewing comfort
• Wide 5mm exit pupil will completely cover pupils to keep the full scene in view and limit disorientation, even as pupils open and dilate in low light

Construction Details

• Environmentally friendly prisms and lenses feature Eco-Glass that is made without lead and arsenic
• Protective textured rubber armoring provides a slip-resistant grip in cold or wet weather
• Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions
• One-piece tethered ocular rainguard protects eyecups from having water pool into them when hanging from the neck, in the rain or from sea spray
• Objective lens caps can be clipped to neck strap to avoid losing them during observation sessions
