  • Description

    Nikon Action Extreme 16x50 ATB Binoculars are a great choice for long range viewing when you need extra magnification.  Features include world-renowned Nikon Eco-Glass optics, anti-reflection coatings, and an All Terrain waterproof, fogproof and rubber-coated body.  Nikon has even included a tripod adapter in this package, for hand's-free observing sessions on any photographic tripod.

    Nikon optics for bright, sharp images

    The high quality Eco-Glass lens elements of all Nikon Action Extreme binoculars are finished with multi-layered anti-reflective coatings to deliver optimum brightness, high contrast, true color rendition and flare-free viewing in most lighting conditions. BaK-4 high index prisms, made with Barium Crown glass, are also part of the Action Extreme design, for sharp images with less light loss than most BK-7 prisms.

    Waterproof and fogproof rubber armored body

    The Nikon 16x50 Action Extreme Binoculars have an ATB designation, which is an acronym for "All Terrain Binocular". In a nutshell, this means your Action Extreme binoculars can go just about anywhere, and perform flawlessly under a wide variety of weather conditions. The Action Extreme's ergonomic body, with its durable and protective rubber-armored coating, is Nitrogen-purged to remove all traces of moisture from its interior, and then the binoculars are o-ring sealed to prevent moisture re-entry.

    No internal fogging, no fungus, no foul

    One of the most annoying things that can happen when observing with binoculars is fogging. Interior fogging of the main objectives happens when minute amounts of moisture enter the system, causing fine water droplets to collect on the glass. Fogging occurs when you are observing in high humidity, or when your binoculars are subjected to rapid temperature changes. This is similar to what happens to your bathroom mirror when you take a hot shower. However, because Nikon Action Extreme Binoculars have been purged of moisture and then sealed, they will not fog internally, and that’s a good thing, since fogging is not just an annoyance, it can cause fungus to start growing inside your binoculars. Even if you feel waterproofing is not necessary for your particular hobby and/or lifestyle, this one result of waterproofing—rendering your binoculars fogproof—should make you a fan of this feature.

    Adjustable eyecups and easy central focus

    The Nikon 16x50 Action Extreme Binoculars feature unique click-stop, twist out eyecups that offer long eye relief—17.8mm— and the ability to vary that eye relief so the user can find the perfect eyecup location for their needs. There's also a diopter control to correct for normal right/left eye vision imbalance.

    Focusing is a piece of cake, too. The oversized, ribbed focus knob is ergonomically placed right in the center of the binocular bridge so that your hands will find it instinctively. Sensitive to the slightest adjustments in either direction, you'll be able to find perfect focus in a snap. Close focus for the 16x50 Nikon Action Extreme model is 23 feet.

    Easy to mount on a tripod with included adapter

    When you will be using your high powered binoculars for any length of time, you will enjoy the option of mounting them to a photographic tripod with the included tripod adapter.  Mounting your Action Extreme binoculars to a tripod will eliminate arm fatigue and image shake, and its a nice way to go if you will be sharing your views with others.  A beauty cap marked with the Nikon logo can easily be removed to reveal a tripod adapter port, and will accept a 1/4-20 threaded bolt from standard tripod adapter.
