Nikon 7x50 OceanPro CF WP Fog-Proof Global Compass Marine Binocular - Black

While the 7x magnification and 50mm objective lenses provide good light gathering, they are primarily designed for terrestrial and marine use. For serious astronomy, higher magnification and specialized astronomical binoculars are generally recommended.

The integral scale on the compass can be used in conjunction with known object sizes to estimate distance. Consult the product manual for detailed instructions on using the reticle for rangefinding.

Multicoated optics means that multiple layers of anti-reflective coating have been applied to at least one lens surface. This reduces light reflection and increases light transmission, resulting in brighter, sharper, and higher-contrast images.

The binoculars are described as waterproof, meaning they can withstand immersion in water up to a certain depth and duration. It is advisable to check the specific rating (e.g., meters for minutes) in the full product specifications or manual and avoid prolonged submersion.
