Technical Features for Celestron Oceana 7x50 Porro

The Celestron 71189-B is an oceana 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, and a convenient individual focus system makes this a very practical binocular. The internal reticle and the calculator dial can be used to calculate the distance and size of objects.

BAK-4 prisms and fully multi-coated optics provide ultra sharp images with high contrast and resolution. The large 50mm objective lens offers maximum image brightness even in low light conditions. This binocular has an aluminum body and is fitted with a threaded mount for use with a tripod.
