The 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 non-slip 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 carry in wet, rough environments common to ski boats, runabouts, fishing boats and personal water craft.
The OceanPro utilizes precision ground lenses with multiple layers of anti-reflective coatings to deliver superior brightness, enhanced resolution and critical high-contrast for low light and bad weather conditions. The large, 50mm objective lenses provide a 7.1mm exit pupil for maximum light gathering, while a diopter adjustment and large central focus knob make focus easy to achieve and maintain.
Two versions of the Nikon 7x50 OceanPro are available, depending on user preference and requirements. Besides the standard version, a model is available that incorporates an illuminated compass for easy direction finding. Each model 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 for each model is 378 feet at 1,000 yards (38 feet at 100 yards). They utilize fold-down rubber eyecups that 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.
