    Overview: The advanced Nikon Action Extreme 7 x 50 is a rugged, waterproof binocular that can be used for hunting and other outdoor activities. The Action Extreme ATB (All-Terrain Binocular) features a durable rubber-armored coating for a sure grip, and comes with a neck strap, eyepiece and objective lens caps, and a soft, padded carrying case.

    Waterproof: The Action Extreme is nitrogen-filled and O-ring sealed to prevent fogging, and to protect the internal optics from condensation and mold. The binoculars should suffer no damage to the optical system if submerged or dropped in water to a maximum depth of 1 meter for up to 5 minutes. The Action Extreme can be used in areas of high humidity or rain without worry.

    Multi-coated Optics: The Action Extreme binoculars feature bright, multi-coated Eco-Glass lenses and BaK4 high-index prisms to deliver bright, high-resolution images.

    Focus Knob: The Action Extreme has a smooth, central focus knob for bringing your subject into focus.

    Diopter Ring: The right eyepiece has a diopter ring for adjusting the binoculars to your eyesight. A diopter index indicates the "0" position, as well as "+" and "-" positions.

    Eyecups: The multi-setting, click-stop rubber eyecups make it easy to position your eyes at the correct eye-point for the greatest comfort during extended use. The Action Extreme offers a long, 17.1mm eye relief, allowing you to get a full field-of-view through the binoculars, even while wearing eyeglasses.

    Rubber Coating: The body of the Action Extreme has a durable rubber-armored coating to give you a non-slip grip, and to protect the binoculars in virtually any weather.

    Great for the great outdoors

    Written by Ralph Graves, Staff Writer - Creative, on 10/23/2013 5:07:00 PM

    Binoculars have a hard life at our house. I don't just sit by the window watching the birds. I use our binoculars when we go to beach, when we travel to the mountains, and sometimes just when we're out walking in the evening.

    The Action Extreme binoculars are decidedly up to the unintentional abuse we dish out to our field glasses. They can handle getting doused by cresting wave, or accidentally being dropped in a snow bank.

    The imaging on the Action Extremes is crisp and clear — and for me, that's not always a given. I wear glasses, and each eye has a slightly different prescription. So if I'm looking through binoculars without my glasses on, I generally can't get the image perfectly in focus. The Action Extremes, however, let me fine tune the right eyepiece. So after I had focused in on my subject, I could make that final critical adjustment to let me see it precisely in focus.
