The Barska 7x50 WP Deep Sea Binocular is designed specifically for the nautical and boating enthusiast. The 7x50 is a popular, easily manageable binocular size that permits a steady image even under agitated ocean conditions. These binoculars provide clear observation in any marine ecology from 'cansee to cantsee' - sunrise to sundown. The Deep Sea binocular features a rugged heavy-duty and shockproof rubber-armor covering that allows a sure and secure grip as the white-caps come with tumbling over the bow. The 7x50 WP Deep Sea binocular has center focusing. It is equipped with a built-in internal rangefinder and directional compass reticle to actively assist boaters with direction and bearing indicators during navigation. A distance indicator on one of the objectives allows distance determination when used in conjunction with the rangefinder reticle. With fully multicoated BAK4 prisms for crisp images, it is waterproof and fogproof and has a non-slip ergonomic rubber design.
