The Celestron 71101 Outland LX 8 x 40 waterproof binoculars are built to withstand the elements. Great for boaters and hunters, but well-suited to any sport or nature activity in which you might rain, sleet or fog, the Outland LX Waterproof Series takes Celestron's popular Outland series to an even higher performance level. The Outland LX features fully multi-coated optics, extreme near focus, and a four-element objective lens for ultra sharp focus across the field of view. With nitrogen-filled and sealed bodies and a protective rubber covering, all Outland LX models are waterproof as well as fog proof.
The Celestron 71101 features an 8x magnification and an objective lens diameter of 40 millimeters, giving it a 5-millimeter exit pupil. (The exit pupil size -- the diameter of the objective lens divided by the magnification -- determines the amount of light available to your eye. The larger the exit pupil, the brighter the image obtained will be. A three-millimeter exit pupil is generally sufficient for daytime use, five-millimeters is suitable for daytime and twilight, and seven-millimeters is generally necessary for maximum nighttime or astronomy use.) All Outland LX models also come with Celestron's No Fault Limited Lifetime Warranty.
