The Oceana 7x50 Binoculars from Celestron are waterproof binoculars designed for marine use, covered with rubber and nitrogen purged for all weather protection. An illuminated compass for direction finding, a reticle for distance measurement, and a convenient center focus system make these very practical binoculars.

BAK-4 prisms and fully multi-coated optics provide ultrasharp images with high contrast and resolution. The internal mil reticle can be used to calculate the view angle, the horizontal view angle, the vertical view angle, and the distance. The reticle uses 10 mils for each number. It consists of a vertical and horizontal scale intersecting above the compass degree scale. A calculator dial for quick distance measurement is located inside one of the tethered lens caps. Used in tandem with the reticle, the distance to an object is determined quickly and easily. This binoculars have an aluminum body and are fitted with a threaded mount for use with a tripod.
