The 7x50 Oceana Porro WP IF and RC Military / Camouflage from Celestron is a waterproof binocular designed for marine use with rubber covering and nitrogen purged for all weather protection. An illuminated compass for direction finding, a reticle for distance measurement, a calculator dial for quick distance measurement and a convenient center focus system make this a very practical binocular.
BAK-4 prisms and fully multi-coated optics provide ultra sharp images with high contrast and resolution. The internal 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 at the end of the left objective tube. Used in tandem with the reticle the distance to an object is determined quickly and easily. This binocular has an aluminum body and is fitted with a threaded mount for use with a tripod.
