Bushnell Falcon 10x50 Porro Prism Black Binoculars 133450 Bushnell is the leading brand in high-performance binoculars, and the Falcon series offers powerful magnification at an economical price. Versatile, and ideal for stadium sports, bird-watching, hunting, and many other outdoor applications, the 10x50 model boasts a durable design and rubberized, abrasion-resistant finish. An InstaFocus lever provides smooth feedback, with just enough tension to fine-tune magnification, while a Porro prism and coated lenses provide sharp viewing. For those who wear eyeglasses, or sunglasses on bright days, clever fold-down eyecups protect your lenses from scratching. Making Eye Adjustments (Figure 1): The distance between the eyes, called “interpupillary distance,” varies from person to person. To achieve perfect alignment of lens to eye, follow these simple steps. * Hold your binocular in the normal viewing position * Grasp each barrel firmly. Move the barrels closer together or further apart until you see a singular circular field. Always re-set your binocular position before using. Improper alignment of the interpupillary distance can cause double-images. How to Adjust for Individual Eye Strength: Bushnell Falcon binoculars utilize the “Insta-Focus” focus system. "Insta-Focus" binoculars have a central focusing lever between the barrels. Focus at any far or near distances can now be attained simply by pressing the “Insta-Focus" lever. Eye Cups (Figure 3): Bushnell Falcon binoculars are fitted with rubber fold-down eyecups designed for your comfort and to exclude extraneous light. If you wear sun/eyeglasses, roll down the eyecups. This will bring your eyes closer to the binocular lens thus providing improved field of view.
