The New Nikon 7x50 OceanPro binocular is nitrogen filled and O-ring sealed for waterproof, shockproof, and fogproof performance. The binocular also incorporates a rubber-armored exterior that provides a nonslip grip and helps prevent sliding on the helm station or console, even in rough conditions. These features, together with tough, lightweight polycarbonate construction, make the OceanPro durable enough for everyday use in wet, rough environments common to ski boats, runabouts, fishing boats, and personal water craft. This model incorporates an illuminated compass for easy direction finding and has a 7.2 degree real angle of view, which equates to a 50 degree apparent angle--true wide-angle performance. The field of view is 378 feet at 1,000 yards (38 feet at 100 yards). Fold-down rubber eyecups protect the eyes from bumps in rough water conditions and provide 22.7mm of eye relief to accommodate eyeglass wearers and non-eyeglass wearers alike.
