Nautic 8x25 is a handy monopodular observation and navigational device dedicated for use on swimming vehicles and in the case of bad weather. The telescope has a nitrogen filling for water resistance and counteracts the internal fogging of optical surfaces. The housing is made of profiled rubber for one-handed grip. The Nautic 8x25 mono optical eyepiece system provides sharp contrast images, and all lenses are made of high quality BaK-4 glass and covered with multilayer FMC optical coatings for high optical performance. With the observation eyepiece I used the retractable eyepiece, which allows users to wear glasses for comfortable observation. The set includes a cover and bow.
